yep - this is exactly why i went the other way around. one of the reasons i came to louisville was because i love its music scene. but being an out of towner, and in my late 30's and TOTALLY unestablished as a musician here i found it easier to get dj work.The point here is making your equipment pay for itself...and taking care of it so it will continue to give many years of service.
I did sound for virtually the entire Mobile Beat Convention in Las Vegas one year at the Tropicana...it took everything I owned, plus everything I could borrow and a few things I had to steal!
I got to town Sunday night and <FLASH> the next day it was Friday morning!!!
Whatever you think you're going to need...multiply by two!
(and you'll probably still be short one at some point)
It's not impossible to do, but like has been pointed out by people with more experience than you and me combined...it ain't easy!
