Building a Chicago Rooftop Deck

I just closed on a small condo in Bucktown on Tuesday. It's on the third story and I have interior access to the roof which is 65' x 18'. In the process of looking for a place, I saw some really sweet decks and got a few good ideas.

I basically want a wooden deck, pergola, and an outdoor kitchen with a garden variety of plants and trees. I can do most of the work but I want the deck itself to be done professionally. So, if anyone knows a good, reputable builder who specializes in decks please let me know.

Here are a few pics of the staircase and the roof.
