Project Budget (USD)
$30 - $250

Project Description:
I currently have a javascript (well, actually it´s three scripts working togheter) that i would like "converted" into PHP with AJAX-functionality where available. The scripts is used to look at arrival and departure dates into Turkey and with the current visa-rules show if your current VISA is enough, how many days you got left and so on.

You can see the script in action here:

and the source-code for the scripts are available here:

The scripts needs to be well documentet (commented) and for translation-reason it should be clear what and where a non-programmer should edit the file to translate the outputs. I prefer one script rather than three if that´s possible. It´s currently a bit buggy (especially the calender part depending on web-browser) so i would need any bugs found to be sorted out too.

PS: I´ve bought a copy of the source-code from BodrumBulletin to use on another site (in another language), but I don´t like the current setup and this is why I want it in PHP + AJAX instead.

Skills required:
AJAX, Javascript, PHP, Software Architecture
