Would you pay for freelance marketing and user research?

I'm thinking about going independent as a freelance marketing and user research contractor for startups. Think of me as one person method, ideo, or other marketing and usability / user research shop without the overhead, but all of the experience.

I can help you package and pitch your product, learn more about what users want from your work, build a marketing plan, and teach you how to do those things yourself.

I'm doing a bit of exploration. - Would you hire someone like me? - What would you want me to do for your project or company? - What would you want to pay hourly or weekly?

p.s., A few of my developer friends suggested that I post this here. Apologies if this feels like spam.
