As a videographer, I get many of my gigs through Thumbtack. As a client, it's a fairly simple way to post your service needs and then receive quotes from multiple providers. Professional providers must pay to submit quotes so it's important to post gigs for which you are actually hiring. I have seen people submit gigs to "test the waters" which is unfair to service providers. But overall, Thumbtack is an effective way to find service providers to meet your needs and that offers better credibility than craig's list. You can see my Thumbtack profile here.
