Wetsuit alterations in Chicago area?

[vjongene]

I have a 7mm semi-dry suit that was custom made a few years ago. I have used it many times, but I am still frustrated by the fact that the arms are a bit too short, so that if I bring my hands together it pulls over the shoulders, where the dry zipper is located. I live in Champaign, IL, and no one locally seems to be in the business of altering neoprene wetsuits. Any ideas about a shop that may do this in the Chicago area?

Thanks already for suggestions.
