Title: My company's main product is a REST API and we've just released a couple of API libraries in PHP &#38; Ruby that we wrote in-house.  Our customers are starting to write libraries in other languages, but we'd like to turbo-charge this process (and help improve quality)<p>We're starting to talk to contractors about paying for open-source libraries - I just wondered if anyone had any tips on this process?<p>Specifically, how much success have you had with day-rates vs fixed-price contracts, how do you define "finished", and how do you cope with project over-run?
