If your main goal is to gain customers, then I don't think open sourcing is the right strategy. It will be a lot of work and I'm not convinced it will actually net you any customers. Your efforts would probably be better spent on more traditional marketing tactics like advertising, attending related conferences, creating case studies, etc. Also, it looks like you are targeting Enterprise customers. Enterprise sales cycles are long and arduous, you might want to chase smaller customers while you work out the kinks. You might want to consider involving a partner with Enterprise sales experience.
