I am an experienced writing professional and thought I would try to generate some side business via Thumbtack. If you don't respond to requests within a minute, you are blocked from submitting a quote. This is not personalized service, but simply who can respond the fastest. I just read other comments on the internet that suggest Thumbtack generates fake requests to defraud service providers. I have never received a response to any request I was able to respond to, nor have I received a quote for any request I posted. I think Thumbtack is a waste of time and money.
