We have problems with spam bots that signup to our newsletter over and over. We also have problems with a php tracking script for Paypal.
We need someone experienced in AJAX/DHTML/PHP that can put a Captcha system on our newsletter form.
The Captcha must be EASY for a human to see/use and make sure that at least most spam bots can't succeed with their spam.
We also need you to fix a php tracking code script that forwards a 8 digit number to a page on another website/server. The 8 digit code is saved in a database of the first server. The script used to work but when we changed to a ajax form for the newsletter it stopped working. We are sure that if you have experience this would be the easiest part of the project to fix
Before we choose you you must show us a sample of what Captcha you intend of installing.
You must have good reputation and if you can start RIGHT NOW that would be a BIG plus.
NO prepayments. GAF Escrow is ok.
Must be available by email & instant messangers like msn/icq/yahoo
