Got an estimate to install a patio cover, is it fair?

The details. This will be a 14' X 20' aluminum patio cover. Demo old 6'X12 concreate pad and remove debris. Pour new 14X20 concrete slab and install 14X20 insulated aluminum patio cover with power for 2 fans/lights and gutters. Estimate is for $15,000 ($53.57 sq. ft.). I don't have any experience with home improvement construction and I don't know if this is a fair price.

What do you think?
