Looking for appraiser-Port Clinton, Ohio area

As the title says, looking for an appraiser. My Dad's GF has several old Chevy's (no one's perfect) that her late husband had collected. She's going to be selling all the old toys to lighten her load before she moves up here to NH. We have found several companies on line that appraise antique cars but I figured I would see if anyone here could recommend a company that they or a friend had a good experience with.
Thanks

Might kill 2 birds with one stone and call Vanderbrink auctions - seems they work the midwest area for that sort of thing.
Might get not only a value, but a way to move them all on with less hassle.

Cruising the completed listings on Ebay collector cars is a good way to get a feel for the market
