Someone

I'm looking to add some minor mods to a registration form. These would be 1)a "CAPTCHA" feature, and 2)"repeat" fields for the initial password and email fields (to prevent errors on sign-up).
I have a GNU/GPL (free) PHP CAPTCHA script to use already or if you have another I would certainly consider it (but please give me a link to a demo, if you have one).
This should be a quick and simple job for an experienced PHP coder, so bid accordingly.
Thanks,
Mike
