Any gig's you plan to do make sure you get everything in writing, if that means having to draw up a contract, so you will get paid either at the end of the night or when a finished dvd is delivered, then do it. Always cover your back! When I first started out in graphic design I got my fingers burnt and tried to get a solictor after a company who didn't like paying their bills, we failed as they went bankrupt; so I got some good advice from that particular solicitor and maybe you might want to do the same thing, even if it is just getting general info on how not to be taken for a mug. Also look into insurance, you don't want someone tripping over an electrical cable or tripod and them injuring themselves... and you being taken to the small claims court... and having your name in all the local newspapers, for all the wrong reasons.
