I took out an ad on Craigslist titled, "Entrepreneurial type looking for unique position with small company." I told a bit about myself and what I was looking for - growing company in need of a "jack of all trades" type. I've had lots of scam responses, but they're easy to spot. The "real" responses have been very interesting. I'm probably going to start up a service business in partnership with a woman who responded to that ad.
