re: Does this quote for a patio cover seem right?

I just did my 10 x 30 to match my custom home. 12x12 solid wood columns, slate tile floor, one side is rock wall with windows, 4 ceiling fans with lights. Shingle roof meshed into house(can't tell it was an addition at all) overhangs match the house, hardiboard ceiling- painted to match overhangs

$15,600

But I hired the subs myself and managed it.
