Thumbtack is an online marketplace for local services,

a free way to find new clients and manage the ones you already have. Just post your service once, and we’ll take care of the rest. Your service page will go live on Thumbtack instantly.

I love the double-decker search form that allows one to switch from the services offering to the wanted ads view in a simply, intuitive way. Fields and labels are cut to the minimum so that the result is at most readable, while a vast range of choiches are given to those who want to refine their search results.

Round-edged textfields and pleasantly colourful tabs convey a soft, good, warm feel.
