Back to your original question - I know several people that have repaired their own fan shrouds, but don't know if they would be interested in "branching out" and doing additional repair work...
However, I did find someone on Craigs List (in the Chicago area) that is advertising fan shroud repair (and other plastic repair services) - here's the link:
