Here you go... your first investment:
http://www.eeebay.ca/itm/Used-Yamaha-80s-Recording-Custom-Birch-Cherry-Drumset-/330602145269?pt=LHDefaultDomain0&hash=item4cf96c65f5Offer $2000 and expect to pay $2500. You can probably rent this kit out for $100-$150 a show. You'll need a snare drum to go with it. Get yourself a 59' Bassman, a Deville, a Twin, a JCM 900 with a 4x12 cab and an Ampeg SVT Rig. Rent 2 guit amps, the kit and SVT for about $500-$600. If it's for a festival, you'll rent it for 2-4 days, charge about $1200-1400, you get paid $300 a day to be there. Laughin' to the bank. Of course, you'll want a bigger arsenal in the end but this is where I'd start.
edit: WTF is with eebay links? Adds an extra e to eebay?
