Integrate Checkout and Automated Logons.

The [login to view URL] site is working perfectly and the testing has to be done in a backup meaning the live site has to be working until the testing is approved. We want to integrate PayPal Express to the main page and the onetimeoffer page and to make sure the same functionality is working for the payments now on the live site. Furthermore, we want to add an upgrade that when customer signs up he/she gets the logons automatically through an email and also that his/her account gets created in our admin area depending on what account did she/he signed up for.
