The obvious suggestion is to check out CPAN. Do a few searches there and see what turns up. If you find something, post it back here and let the rest of PM know. :)

I do have a comment though - I've never heard of a Perl module being sold, for any amount of money. Perl is free (at least if you get it from CPAN ...)
