It's a shame because they could be a really great company but as I've learned when you have to deal with lots of different people vs one person that does the work and then you pay them, lots of quality, credibility and efficiency gets lost in the long list of different hands.

Just google and read and watch online tutorials and you can do it on your own :) Happy renovating people :)
