Upgrade me php script.

I need some one to update my existing php script. I need you to study the script and add a couple of features to it. Its a fairly easy job if you know what you are doing. I hope for some one to work for a 10 feedback or for a cheap amount of money. Things I need - Login Password ( My current script allows the user to login using just their email address, I want to add a password to it ) - Add another field ( I need a extra field where the user can see the text that I enter for them on the admin panel. - Members can change their information and a couple more if I think of any. They are very easy.
