Growthhackers.com

Inbound.org

reddit.com/r/entrepreneur

reddit.com/r/startups

Those are most frequented by marketers with /r/entrpreneur + /r/startups also frequented by sales/business focused people.

If you post something on any of those communities with some details (I recommend posting to all 4), than you should get some candidates that are well qualified (depending on the project).

I can vouch for /r/entrepeneur and /r/startups. It's my first time visiting both inbound.org and growthhackers.com, they look like excellent resources too. From a quick poke around they seem to be proprietary CMSes \ community software, anyone know if I'm wrong about that?

all very good resources. the key is to pitch to people without pitching them, and without giving away your idea to the world!
