This is actually a little tricky...I don't know how to do it without submitting you a quote for a project. Its not like Soundcloud where there's an open profile everyone can simply view.
Just so you know, the pro pays every time we submit a quote. So every time someone posts a job, you have to pay to bid on it....that catches a lot of people off guard.
If you were wanting to check out the service, p.m. me your email, and i'll send you an invite. Follow the links on the invite, and it'll give us both free bid credits if you use my referral link. I think you can only view my profile if you're registered as a competing pro in my geographical area. But if not, I'll email thumbtack and see if theres a way to just show the profile.
