Hire the core maintainers of projects which are mission-critical. It's an old idea, and a proven one. Anecdotally, I made my living as a such a hire for nearly a decade. Another good plan, mentioned elsethread: have your current devs contribute. Opportunities to contribute always arise, and contributing is in the company's interest. The only thing typically standing in the way is codifying an open source policy (which is a good idea for large organizations.)
