When you say central Ohio, that can cover some pretty large areas. As a semi-truck driver I go down US-30 far too often

You should probably try local camera stores first - I have three places here in Madison Wi that will process 120 format C41 and can print 6x7 or smaller negs.
Failing that, there is a lab here in Madison,
http://www.burne.com that is excellent and reasonably priced. The other place I'd suggest you look into is Dwaynes photo -

Hope this helps,
William
