You could do worse than connecting with Bryan Eisenberg -- see

He's an undoubted expert in the marketing business, with special reference to the web.
There's also Michael Katz, who's a widely recognized guru in the e-newsletter field -- see

Both of these guys have, to my mind (and I'm sure I'm not alone in the opinion), an unparallelled understanding of what's involved in "selling anything to anyone."
They also have an infectious sense of humour -- Michael Katz in particular.
