Typically with things like that, it's not a matter of money. I doubt you are going to find that magic piece of paper to tell you how to do it. The guys who do it have done a LOT of trial an error to come up with what they do. I doubt they'll put a price tag on it unless you are buying the whole car.
My suggestion, go talk to someone who has built a tube frame chassis; tell them what you want to do; and have them give you suggestions on how to begin. If you already know how to begin, quit posting and start building.
