Another suggestion wouldbe toget together with alocal, but fairly high-profile, charity. They will often have a list of regular sponsors. If you say that you're doing this show for charity, and all you want to do is break even, than many groups will be more willing to donate money to your production costs, in return for being named official sponsors. This could help you generate funds for buying more lights. Another fun idea is building your own quasi -
PAR Cans (well, makeshif ones, anyways). A store - bought floodlight with a coffee can attached as a barrel will work for some uses. Just find a base where you can screw the
bulb in, that won't make it hard to attach the barrel, and then find a way of attaching the base with the bulb securely to the barrel, and hook it up to your
dimmer rack, and you have a fixture.
