Cleanup was a massive $$ maker, I bought 2 skid steer machines, 2 stump grinders, chippers, more chainsaws then I can count, trucks with dump trailers and all types of other stuff that I could get my hands on, and they still needed more around here, we worked 7 days a week 14 hours a day for 4 months and it still wasn't completely cleaned up, I spent 4.5 months in a trailer park cleaning it up, and then tearing down 600 trailers, all in total they tore down 1125 of 1270 trailer in just that one park.
Biggest problem was couldn't get my hands on any more equipment, had to buy everything new, and still couldnt get all we needed.
