I have a HTML site (about SB and Dir Submissions) ready but I need a script which does the following:

1. Register clients for taking orders
2. Client area showing the following

1. Previous orders
2. Order Status
3. Order Cart
4. Client Details

3. An order cart

It should similar to the CMS at submitintime.com

If anyone knows where a similar script is available, please mention it ASAP.
