AI coder needed

Hey I've got a great FPS project right now that I'm working on solely. I've got the basic AI bad guy that I took from the Advanced 3d Game Programming book but it sucks sooo bad the way it is, something is wrong with it and I really need someone to take a look at it and improve it a bit. Right now he runs at you and shoots at you MOST OF THE TIME but often just stands there and doesn't do anything or looses you very quickly and then stands there and doesn't do anything even if you are dancing all around him. If anyone has the time to help me out I can send you the .cs that I have of the AI so far. Of course you'd get game credit. Please email me at jpetrilla@mail.com
Thanks
