Project Budget (USD)
$250 - $750

Project Description:
I have a PHP script for affiliate websites with product feeds from ClickBank, Amazon etc. as well as article and news feeds.

The script has some security holes and was attacked by hackers a couple of years ago and I quit selling it. However, I would like to fix it and bring it back. What I would like is someone who can fix the security holes and update a few things.

I realize you probably cannot give me an exact quote with this info. However, if you give me a rough idea and let me know what you can do, I will contact you later and let you take a look at things for a more exact quote.

MySQL, PHP, Software Architecture, Software Testing
