If you're looking for a suggestion of things to do, I can tell you something that the posters of the original ad didn't do that rubs me the wrong way: Respond to people who have emailed you, even if it's just to say "hey we got your email".

I emailed the company from the original ad because we may have been a great fit (seemed great on paper at least), but heard nothing back at all. Who knows if they put a typo in their throwaway email address, or just don't care; but to me it says a lot about how people run their business.

I know it certainly killed my interest in whatever they were working on.
