Need twitter script updated

I have a web based twitter script that I am needing updating to. For some reason, it is not wanting to follow users anymore on twitter. It shows that it follows them within the twitter script on the web side, but really it does nothing. It use to work fine. It has recently been transferred to a new site, maybe that could have caused it... not sure. These are the things that need to be updated to work - Twitter followers - Twitter unfollower - User authentication test (when user is adding a account in, he/she can test the username and passowrd to see if it is right with twitter. right now it just says it good even when it is not. so something minor). That is basically it. I am looking for someone that is REAL experenced in php web development and familiar with twitter. Deadline for this project is a strict 3 days max. The sooner you can get it finished, the more i will pay you.
