I think I may be out of town that weekend (!)

Not sure what kind of DJ's you're looking for, but the guy that did the bar room may be available (and has his own equipment)
He's Dr Fiasco in my friends list.

Also, there's a great psy-trance troupe called Mistress Of Evil who has an awesome roster of folks - www.mistressofevil.com/
Not sure what they're fees are, so you should contact them if'n it's a sound that fits.

I've got a few lines into other folks that may be available. PM me with deets so I can best direct you!
