I am actually in need of an underemployed physicist. I'm writing a book about quantum mechanics and I need a consultant to make sure I get the math right. I was going to put an ad on Craigslist, but maybe someone here has a lead?
I don't know if he does this sort of thing, but I recommend Jonathan Walgate. He has a Ph.D. from Oxford in quantum physics and a business helping people to write grants. He's also a great guy! (I used to do quantum physics.)
