Ask HN: Are tenacious salespeople/marketers here?

I think a team which includes a great hacker, web designer, and marketer is a killer combo. A reason power is shifting from investors to founders is because such a team can go far enough to gain traction and profitability without requiring a cent of investment, especially if they refuse to quit and keep iterating on ideas. It seems pretty easy to connect with great hackers and designers, probably looking no further than right here at HN. However, I wonder if finding great marketers is as easy. I don't mean marketers that focus on online tactics like SEO, SEM, social media etc. Anyone involved with Internet startups will likely be okay with picking up slack in those areas. I'm talking about a different personality type. I'm talking about traditional sales -- picking up the phone and cold-calling, or pounding the pavement, just doing whatever it takes to get the sale. There is a whole world that still doesn't know any more than what they need to know, or may have heard casually, about what's happening on the Internet. To reach these people ideally you will have a tenacious marketer. Paul Graham says his company Viaweb had such a person, someone they could call "an animal". My question is where do you find such people?
