Online Branding and Package Design

So far, my experience in IM has been lots of fun. I've made no money at all, but I've had a blast designing and developing products. I'm wondering if my best bet for making money is to stick with what I do best, which is design.

I'm thinking about creating a Branding and Package Design service. Basically, I'd take a product concept and build a look, or a vibe around that product. I do things like effective color schemes, ebook cover or other package design, and other elements of the branding process.

This Branding service would give any product a more professional look, and ideally improve sales. There are also opportunities outside of the IM market as well with things like product mock-ups, unique avatars, and other non-sales related purposes.

I'm really just trying to figure out if this would be a profitable service. I've seen people offering ebook cover design for over $100. That made me think that I could make some money with my design talents. Please let me know what you think, or if you'd like a box of your own.

Thanks,
T.R.
