That's a cool idea.

I would recommend getting references from everyone that you know - friends, neighbors, etc. Weigh the references against the individual, i.e. are they the type that would be fine with mediocre quality? I would suggest at least three quotes, and consider all factors such as their timeliness to the meeting time, professional competence, and their willingness to work with you.

We also always DIY, but are hiring concrete work for a 3rd garage addition that I will be framing and finishing. I hired the contractor that showed up on time, responded quickly with a bid then followed up, and seemed to be the most professional and competent. He was also the most highly recommended by friends, go figure.
