started a small press and learned everything from the beginning and doing all the work myself

Wow! Congratulations -- you must be really motivated. *g*

Sales -- at Tor, at least -- is a very complicated thing, and I'm not entirely sure exactly how it works still (and I am also not sure what's proprietary information and what's not), so I am going to play it safe and not say much. But I will say that there are a whole lot of people on our sales team and they are separated not just by account, but also by regions of the country.
