Just remember, at 270 hours, two years ago when pilots were being furloughed by the 1000's from airlines, I got a job flying skydivers for $400/week in a 182. It went to $500 2nd year, and I got KA90 time when I broke 1000 hours. I also had no family help getting the job. If I had stuck around I could have flown the turbines at between 750-1000 a week.
So go do it for free, but your cutting yourself short.
