This is a topic I could talk about in great detail...I wrote some fairly detailed posts in another detailing thread on here a while back. If you have not been over to the Autogeek forums I would highly recommend it. You will learn a lot about detailing. If you are going to make any sort of business out of detailing it is in your best interest to become as knowledgeable as you can about proper detailing technique. There are a lot of weekend detailers out there who have really poor practices. I also highly recommend buying a copy of Mike Phillip's book:

There are a lot of misconceptions and misinformation surrounding detailing. It might sound ridiculous, but most folks don't know proper washing technique. I have seen it time and time again where folks put more swirl marks and scratches in their paint from their poor washing technique (trust me I have done paint correction on many of them). Most know little about modern day paint systems (or even single stage paint systems) and quite frankly, most could care less. Most don't know anything about paint correction (compound, polish, seal). None of this stuff is rocket science - it is pretty simple stuff, but again most folks don't care THAT much about keeping their paint in new condition.
Today's paint systems, comprised of a base paint followed by a clearcoat can be very scratch sensitive. Different car manufacturers have very different paint systems. And these paint systems can completely change year to year and sometimes batch to batch. German cars tend to have really hard clearcoats. They are easy to scratch and can be a pain in the ass to perform paint correction on (using a proper dual action polisher). Others have relatively soft clearcoats. They don't scratch as easy, but they may have more issues with marring. Single stage paints (used before the mid to early 80's - before modern clear coats were introduced) can be nicer and easier to work with any many ways. Most airplanes are single stage paint. I am sure many of you have seen an old Mustang, Corvette, etc with old oxidized paint - it looks chalky. In many cases that can be completely restored to a show car finish. It is quite amazing. See here for an example:

Sadly you can't "restore" modern clearcoats. Once clear coat has failed you ain't fixing it. You have to respray the entire panel. The goal is to maintain your paint and prevent the degradation of clearcoat before this ever happens...Here are some examples of clearcoat failure:

I have been pretty involved with detailing as a hobby since I was in high school. I don't have nearly the time that I used to so I don't get to do a lot of detailing work anymore, but I still make sure to detail my truck and airplane on a semi regular basis. Reality is you would have a hell of a time trying to make a living by doing a simple bucket wash. You can, however, make a pretty good living by doing quality high end detailing. There are folks who pay WELL over $1000 for a show car detail. Detailers who cater to these types of jobs can do very well. I am not sure why, but there are a lot of really good high end detailers in the Northeast. Here is a really impressive high end detail on a GT3:

Another option is what I would call "middle end" detailing. Services ranging in the $200-$500 range. Many of these guys are mobile detailers with a detailing trailer to perform all services at your location. I imagine these guys can do pretty well if they have a good base of clientele.
I really try to avoid car washes as they tend to put swirls and scratches in your paint. Touchless car washes are your best bet if your really set on a car wash - if I am really in a pinch I will use one of these. Even then I try to avoid them. I get a real kick of out some of these folks who make a scene about their $20 car wash and how dissatisfied they are. LOL.
I'm not saying you couldn't make some side money doing a typical bucket wash. Reality is there are more people willing to spend $50 on a wash than there are a $200-$500 wash. Most are satisfied by that $50 wash and there is nothing wrong with that. Whether you can make much money doing it...I don't know. The best thing you could do as a detailer would be to educate your customers on paint, proper washing technique, etc.
I have a pretty decent Detailing "How-To" that I wrote up a few years ago on Word. If anyone is interested let me know and I can send you over a copy. It is a decent resource and quick guide to what I would consider is a "proper" detail. As always, if anyone has any questions about anything detail related let me know.
EDIT: Few more things I would like to add.
Professional Grade products do make a difference. None of my products are from Walmart, Auto Zone, Oreilly's, etc. That said...there are some great consumer grade products out there and to be honest any of the Meguiar's consumer grade product is pretty good. The best bang for your buck in my opinion is Meguiar's Professional series of products. They are sold in gallons and are concentrates, which go a long way.
I have many other professional grade products as well though (McKees, Detailer's Pride, Wolfgang, Menzerna, HD, Collinite, Pinnacle, Blackfire, Sonax, CarPro, Optimum, etc...). All great brands. It is kind of fun trying all the different products.
I have a full write up on a detail I did on my truck over on AutoGeek, but I can't find it.
Here are some photos (I have interior shots somewhere too):
