Few tips:

Charge people at the door. Don't pay the bands get donated prizes from local companies (i.e. sports tickets, movie tickets, gift cards, studio time...ect.) Have bands sign an "intent to compete" contract that includes clauses that say the band forfeits all prizes and is liable if any damage occurs to the facility. Tell all the bands they all get the same amount of mics (7 drum, 1 bass, 3 guitar, 3 vox) and the same amount of imputs and monitor mixes NO MATTER WHAT. This eliminates a band wanting to bring their 32 piece kit or to have a 13 piece orchestra. Also they all need to told they all have the same amount of setup/line check/sound check time (say 20 min) this keeps bands from getting super picky with their mixes and keeps the playing field level. Finally just generally schedule the crap out of it. All the bands should know when to show up, when to set up, when to be on deck, and when to play. Don't let them bring friends in for free (or you don't make money.) Battles of the bands can make lots of money if you make it compelling to compete, and limit your talent, 4 or 5 good bands competing will do the best. Hope all this helps.
