Prestashop sales man management

Dear Sirs, I need a personalization for my prestashop 1.4.7.3. I usually add from back office sales man to let them login to admin interface. This project is composed from a back and front office personalization. On front office: when a customer do registration he will select his salesman. After login customer can see all him salesman information: name, surname, skype, tel. On back office: 1) when I set a new sales man on back office I can insert also his tel. and skype. 2) The salesman can see on orders tab only orders made from customers which has selected him as salesman on registration. On the end of page I can see the total amount of goods sold without taxes and without shipping costs. 3) On customers list tab salesman can see only his customers. 4)If I login different from salesman I can see everythink as usual on both orders list and customers list. 5)In case I login as admin I see a new field each customer on the customers tab, this field is the customer's sales man associated. I can modify and select an other salesman if needs . Please insert "selller tabs" in the message to let me see that you have read my project.
