I'm a freelance Ruby on Rails developer located in New York City, and the number of interested clients has become increasingly large - large enough that I'm very interested in hiring a few consultants of my own to do the cookie-cutter business logic and CSS/HTML work that I'd rather not do. Does anyone have experience doing this? Positive/Negative? Is it a lot of management overhead, and in the end is the extra throughput worth the stress of managing subcontractors?
