Heh heh, You're running into that "hmmm, ok this is getting boring, what's next" phase. Well, you have a plane, do you have your commercial yet? Pipeline patrol would be available, you could pick up a couple of mainline routes to start with, lease direct to someone with contracts or try for your own, Call Conoco pipeline division, they were a good outfit, call whomever. Collection fields you need to be comfortable at near aerobatic routine performances below 150' while tracking which pipes are yours as they twist around the pumps, tanks and valves that 5 companies maybe with multiple surface leases sharing across a field to a transit station/pipe. They are tough and you should probably have 10 hrs aerobatic training and a couple hundred low level transit pipe patrol hours (call it a month on the job working a plane for a living) before taking one on. You'll need a bunch of dual on those learning them anyway. Best to stick to transit pipe.
