So take your 20 man project - all of it - and give the entirety to the Ph.D. In fact, since you'll be saving so much money, get three Ph.D.s to work on it simultaneously and independently. In fact, tell them it's first to publish - sorry, I mean launch - and you'll probably see them work 24/7 until it's done. In fact, what you've just done is start an industry funded research project. You should now go to a university, "collaborate" such that they get to put their name on the project, and you get to harvest their Ph.D. candidates for minimum wage, and you're laughing all the way to the bank!
