My question is: Should I get a dedicated marketing persion on board, and if so, how should I go about finding and selecting them?
EDIT (in reponse to revorad)
A little more detail:
Bouldr (http://bouldr.net) is a worldwide guidebook for rock climbers and boulderers.
I'm in the process of building an iPhone application, and have released the first version already this year. From that, I drew on feedback, and have made numberous improvements and changes. The next version is just about ready, and once the last bug is smashed into the ground, I'll be submitting it for review.
I'll be building a free version of the app too - I'm building the paid version first so that I can get feedback from people that are genuinly interested in having Bouldr on their iPhone.
Ideally, I need to get lots more people adding and updating the site, and in order to do so, I think I need help from someone with the experience necessary to carry through.
I have a facebook fan page (http://facebook.com/bouldr), with ~14k fans, so I think I'm doing something right, but I also suspect that the message I'm sending is confused or at least not consise enough to stick.
