Freelance is company for people just like you actually! We're an online system that helps freelancers (designers, artists, and all other creative types) manage their invoices, time, projects, client communication, etc. in one suite.
What we imagine for this logo is just the text Freelance. We can't think of any icon or symbol that would encompass all creative types. We wouldn't want the logo to be a pen tool icon or some other graphic design specific icon. We need the logo to be versatile in that any freelance person can connect with it.
If you can think of an icon that will work, go for it! If not, we'd really love to see just a really clean type-based logo with our name. Thank you!
