Simple job, working on my existing PHP site (cal)

We have an existing PHP site with a MySQL database. The site is split up into different sections (each represented by a directory of its own). We need some work done in only one of the sections, which is some simple Google Calendar integration and basic PHP code - some of which already exists elsewhere in the site which you can copy. Please read through the attached document for detailed instructions and feel free to ask any questions you may have. You will be given full ftp and cpanel access and my Skype username for extra communcation if necessary.
