Minor tweaking to a PHP script

I need some minor work done a PHP script. The script has some "bugs" that are not working properly and I need it to function properly before I release it to the public. It's a small project but I will also need someone reliable to install the script on a regular basis so this could be a long-term assignment. I work with affiliates to promote the script so it could be a worthwhile project and continuous income. If you are not reliable, please do not bid.
