You are getting quite a bit of good advice here. May I ask how old you are? Do you actually have an engineering degree? It is good to have dreams but you have to keep your feet planted in reality to make your way successfully. I would also advise taking one of those job offers, file your custom boat away for a later date and work towards your goals with a positive cash flow. Btw, that design looks like bigger seas would slap the shit out of you by way of the big flat frontal area between the sponsons, I would definitely have a good naval architect look that over before you built it. Good luck in your endeavors.
