Start hitting the local shows and "scene" and talk with the guys whose cars you're drawn to. Find the guys that have done the majority of the work them selves and need a jump start.
Offer to supply the space and a lift, some cool tools and have them build you a car. You pay the hourly that's agreed on, maybe split the profits of the build. You get a relationship started, see the work ethic and aren't out too much money.
I know of a couple talented people that all they need is a car to build and someone else to pay for it.
It's that easy.
