As Charles has pointed out, the maintenance side is a real bear. You will need to write a PRM exam, and then be accepted by your PMI (principle maintenance inspector).
You will need to write a Chief pilot exam, you will need to have a Company Aviation Safety Officer, etc. etc. Small things like creating a passenger safety briefing card become HUGE issues.
Once that is all done, you will find that you will work WAY harder for way LESS money than you could possibly imagine. My advice: you better have some other reason (ie pursuing a particular lifestyle) for doing this than getting hours, or getting rich.
As far as the Chisel Charter thing goes, be VERY careful. If the folks who HAVE put the time and effort in to do it on the up-and-up catch wind, you will likely find yourself up against charges, or up against a back wall getting beaten, or both.
If you do decide to pursue this, feel free to PM me any questions. Willing to help.
