Thumbtack is a Rip Off. You can contact prospective customers for FREE, BUT when/if the customer replies back to your offer (either YES or NO) you are charged LARGE amounts.
A customer responded back to an offer I made, simply to tell me that she was already working with someone else. Thumbtack hit me with a $9.84 fee.
I contacted Thumbtack to dispute this charge, but they only agreed to give me a CREDIT. So guess what eventually they would have still get my $9.84.
They refused to refund my money to my card, unless I Deactivated my account.
Plus, the representative who assisted me was extremely rude, nonchalant, and careless.
Goodbye Thumbtack!
