Looking for a listing directory for building companies


we are going to make a concept and portal presenting different kind of contractors and building companies.

Any tipses on themes and a good listing directory for this?

We want to present each company by regions and the different offices they have in our country. Present them with a longer and good article, some images, contact info and related info on each presentation page.

Also featured listings would maybe be interesting.

Any tips on great listings components / and a good nice looking theme?
