Yep they are on there.
They have nine reviews and are rated "A"
I only read one review that said they wanted to be paid in cash (huge red flag for me, I don't hire illegal workers and believe that the only other reason would be to avoid paying taxes) The reviewer also said he paid for 2000 sq feet and it should have been 1700 sq feet. He said that was his mistake as he didn't double check the measurements until the job was done.
I have lived in the phoenix area for a bit over two years. We moved here from Washington state. I don't want to sound negative but I have found the contractors that I have dealt with here to be less than ethical. I use Angie's list and the Better Business Bureau as a reference but my advise would be to get everything in writing, check to see that they are licensed to do the task you are hiring them to do. Example, I hired a licensed contractor that installed cabinets and epoxy floors in my garage. Turns out he wasn't licensed to do epoxy floors, just the cabinets. He did a terrible job on the epoxy. After a battle that involved the state I was refunded the cost of the epoxy floors.
My best advise is CYA in every way you can!
Good luck
