i tried it but the fact you have to put in a price i found annoying, if i am getting quotes i want just that quotes you tell me and i will judge on how i feel overall i don't want to just do the job for a price.
I think i used it twice and both times after a few days got the sorry email, i like truelocal.com.au which uses the local paper search so you tend to get local tradies who actually don't mind showing up and quoting.
