Based on the requested feature set, I estimate this would cost $300. If this is acceptable to you, please email us using the Contact Us form here: http://www.dragonbyte-tech.com/contactus.php and I'll get a contract drawn up.

$300 represent at least 5/6 with existing programs update a life.
Especially for a change not so huge a free program.
