I never built a scale Tube chassis until i did my 57 promod, Like you i contacted people to build me a chassis and in the end with some encouragement i did it myself. I wasted alot of rod myself, and i don't care who the builder is even the best guys have waste from stuff not turning out right the first 2 or 3 try's. like suggested above try sticking with it and you will be surprised what you can do, reference pictures are you friend as are other peoples build's. Don't be afraid to ask questions about doing certain parts of the cages etc.
