AJAX intergration in XML / PHP file

I need someone who can put a calendar in my script. The calendar will be in a popup So the job is: - implement the calendar without changing any code! in the script xml file. - make it bug free - in W3 standard ([login to view URL]) - for multiple use (for several popups from 1 page) - the popup should be placed some where else in the page than right next to the the button only. - fix the selection issue...: Now a visitor can select day 1,2,and 5 in the calendar but a visitor should only be able to select connecting days also if this overlaps 2 months... Example: (okt) 30,31,1,2 (nov) This job should be able to fix in a couple of hours. I am looking for someone who can do this quickly and proffesionally Fix asap. I will send you the files in .tar when you leave me a PM. 1 script file (plus 2 includes) 3 calender files (plus a couple of includes and 5 images.) You have to have very good knowlegde of PHP, AJAX and JavaScript!!
