If your client may object to the open sourcing of your CGI, request that one/more of the monks operate as a closed forum for ratifying the code. Perhaps you'd find some willing to do this..
Personally, I can't think of a better group of people to go over some Perl than the guys here, and even if it
take a donation to the monastery, at least you know you're getting good quality advice for the cash.
