Should a start-up wait until it finds the perfect team?

Should a start-up wait until it finds the perfect development team, or should it just hire whoever is available and try to manage it along? I am working on an idea now, and I've interviewed a couple of devs for it. In general, resumes I have received have been good and the candidates have been okay, but they are not my dream team. I know a couple of developers locally who I would love to have on my team. They get it, they're self motivating, and they are fun to work with. However, they are fully employed and risk averse. Should I give up my dream of finding the perfect team and just hire based on availability and price?
