Best of luck to you building your first house, it’s an adventure. I
would recommend talking to your neighbors and friends and see if they know
any contractors they worked with in the past. Since I’m sure you
already did that you should try http://www.jobtrio.com/ I found that they
have a very easy to use search. They have the biggest list of contractors I
have seen to date, plus you can write reviews and read their articles.
