I'm a marketing, design, brand development, and writing consultant. Would love to help out some other companies in this area... maybe I should post on the wiki =)
One problem is that many of these startups are offering very paltry "bounty's" for the work that needs to be done. I'm happy to offer discounts off normal market prices for this work, but people still need to be prepared to pay for quality.
on the one hand i agree, but on the other it's also a matter of profits being made, people will always be loathe to give away more than they're earning without knowing the size of the market. i think you'd be better off trying to make your services as cheap as possible, to begin with at least, and grab the first to market advantage in anticipation of a bigger one!
