I too have rented some 182's, but ancient history and irrelevant....for the record, the most recent was a 182P about 21 years ago...and that was AFTER the big spike in rental pricing that seemed to happen around 2,000, and I could be off base but I
want to say it was ballpark $130 to $140-ish...worth about $235 today if you believe google.
I think maybe two years prior I rented a 182 RG for that or less!
...whatever it was I felt like I was getting robbed back then...i was right after 172s jumped from $60/hr to around $100/hr.....so maybe $30 or $40 more than a C172.... $40 adjusts to about $84 today...so that checks to $200-$230 ish today.
There is a 182T near me that rents for $250/hr

if the pictures are correct, it looks like it might be a nice one so maybe worth a bit of a premium.....
As to the how many hours.....
I think a lot of that would depend on you and your logbook.
