Steve:
One way to find timber framers in your area is to go to the timber framers guild home page and click on resource guide. Then select timber framers and enter your area by state. This should provide you with a list of names, addresses, business names and phone numbers, with email addresses and web pages.
Also you could try the link to the timber framers business council. They could help you find timber framing companies in your area.
Good luck with your project.
