Adjust Current Sites JQuery and PHP form mail script

I need a simple adjustment that I dont have time for. I need the current form mail that implemented into a jquery slide out form and a box (needs to be changed to use modalbox - I have the script, just need to configure prototype to work with JQuery) I want the "MAIL SENT" message to appear within the form, without taking the user to another page after the mail was sent, instead just bring up a message below the form or some other method without leaving the page. (iframe?) [login to view URL] Please see the website above. One JQuery form slides out from the side (on the left) captioned "CONTACT" and another by click on PRICE REQUEST link brings up a box (needs to be changed to a AJAX form using the example below - click see demo after following the link) - MUST BE THE SAME EXACT FORMS THAT I ALREADY HAVE, BUT IN AJAX... (BOTH ENGLISH AND RUSSIAN) - forms are READY, just need to be implemented into new ALREADY created code. [login to view URL]
