I work in the book business (retail side of things). You are going to have a hard time finding a publisher that would be willing to print a minimum print run of a specialty title. Every year, more and more smaller publishers close up shop and the self-publishing market picks up the slack. Major publishers only want big print runs and guaranteed (to the greatest extent possible) likelihood of selling through print runs.
I'd recommend you research local interest publishers that specialize in local history. Arcadia Publishing and The History Press are the two publishers I know that are in this sphere. I am not sure if they do coffee table books (I've never seen one from them). I think getting a publisher interested in this type of thing as a coffee table book is going to be challenging.
You need to figure out what the publisher wants to hear. Who is going to distribute it and who is going to buy it and is it worth their investing resources, is it worth a minimum printing. Will retailers actually want to carry it? Its getting harder and harder to sell books every year, publishers want certainty, to the greatest extent possible. Retail store managers don't want to buy stock that just sits on their shelves (local interest titles usually do...).
I suspect you'd have better luck with the self-publishing route. Though, if you want a quality product, you need to be careful. Self published print-on-demand books have improved in quality in recent years. But I can still instantly tell the difference between print-on-demand self -published books and books with actual print runs. Quality coffee table style is probably going to limit your choices and significantly increase the cost, to the point it may be hard to get people to buy it.
