I would like to build my next development using large logs or timber. need info on locating, selecting type and sizes, cost and delivery. I also need framers, enginers and contractors

I would suggest you could go to the timber framers guild home page and 'click' on resource guide. Then select what you want: timber supplier, framers, engineers, and/or contractors. Then add your area. This should give you a list of each to start making your calls to.
If this all fails you could contact the timber framers business council and they could refer you to people in each of these categories. Good Luck, Jim
