I've only been in this field for a year , but based on what I've learned I do not think that budget is unrealistic.
You stated that the finished truck could "easily" be sold for a price that would recover your expenses. That is not realistic. Forget about getting your money back - just decide if you want that build.
You are clearly apprehensive about the situation. I think that you should give serious consideration to alternative courses of action. Maybe you want to drive your patina special as is. If is is still original , it would be easy to sell ... take the proceeds and couple it with 2/3 of that build budget and buy a resto-mod that is street ready. Let someone else take a bath.
You stated that you were "shocked" at the proposed price , and that you felt it to be "outrageous". You clearly don't want to work with that guy - you don't trust him. (Through no fault of his , I might add...)
Formulate and follow Plan B.
