Carpenter Job in Houston, Texas

I removed the backseats out of my 2007 Saturn Vue, I want to put a bed frame back there, 69 inches by 32 inches. The legs behind the front seats needs to be about 11.5 inches tall, the legs in the back needs to be about 1 inch tall to be level. I want to be able to fold the bed frame in half, so that I can access my spare tire. I'd also like the bed frame to be painted the same grey that my car interior is. Willing to pay a flat amount for the whole job, including materials.
