PHP Software Edits

I need a professional PHP coder to edit an affiliate software that we have on our site. Anybody that really knows PHP can do this in a short time. The simple requirements are below. 1. Set up a cron job to make the calculating feature of the software work. 2. Fix 3 errors that the software is giving me (page not being found, 404 error, and an Apache error). 3. Change a number that was put into the software that acts as a prefix to the actual affiliate number. 4. Change that same prefix number in the API code that goes with our pay card company. It's a link that is used to send the number and other info to their site when it's clicked from the affiliate back office. 5. Install a "logout" link in the affiliate back office. 6. Fix a glitch in the admin panel so that it will work with the affiliate back office and web site dynamically by making the html site PHP pages. 7. Check the system emails and make sure they are coded to work with the system and not be hard coded. If you know what you are doing I'm sure this can be done in less than a day.
