I have seen what these specialty shops charge. I would find individual shops for each of your projects. A small custom cabinet shop could do your desk, and a upholstery could do the chairs and widow treatments, and so on. I am setting up a shop out of my house to get back into cabinet/furniture making on a small scale. My wife is getting a mental list, I can tell. I made our dinette booth in our MH and found a local lady to cover the the foam cushions, she did a great job with the beading and lining up the patterns.
