43852 E-Mail+ system like Gmail

Arijit: I have made this a private project listing for you only. As discussed, I will be charged $400 USD for your services and you have 30 days to complete this project. I will definitely leave you a good rating once this is done and I am sure there will be future projects for you to work on. The most important thing is to build a good relationship. Please design the e-mail system with AJAX. The concentration should be on speed, features, and integration with my existing site. Also, you will have this installed for me, unless otherwise noted (you must also send me a copy in a zip file of the script for backup purposes). Thanks! Please refer to the following file attachment for the remainder of the details.
