Timber Framers Guild Forums General Barns and Traditional Timberframing Looking for resources on barn repair.

Ok, so I have met Tom Nehil, of Nehil-Sivak Engineering in Kalamazoo, through a timber framing course at Tillers International. I imagine he would be an acceptable trained eye for such a project and familiar with the local timber building styles and structural requirements. What services should I be requesting from an engineer for a project like this? Any guesstimates as to the cost of such a request? I imagine the benefits would certainly be worthwhile and valuable though there is a limit to the repair budget for this simple barn.
