I once thought like that, until an accountant friend shared his point of view on the matter. That project you don't want to do, what amount of money would it take for you to accept that project? I'm not talking about what you think is a reasonable amount based on the work involved, put those thoughts aside. How much money would it take for you to actually be happy accepting that task? An extra 150K$? 500K$? 1M$? Because that's what you tell them your price is. They can shop around and go elsewhere if they choose, but don't immediately respond with a flat refusal, because this is an opportunity for a win-win.
