Angieslist had it right from the beginning! The customer (not the contractor) joins the site for a reasonable fee and searches to their heart's content.
That way of doing business eliminates the tire kickers and those who only want a job quote! I've been in business since 1994 and figured Thumbtack would help fill the void between larger jobs. In the beginning, their pricing structure was fair. Now, being charged for a lead before I even view it is ridiculous. I think my relationship with this organization has run its course and I'm about ready to jump ship too!
