[SL] Username joe and customer Joes Deli

[WJ B. <wj...@pa...>]

How can I setup a user called Joe who is also a customer called Joes 
Deli to access SL.
Joe does not need to access all the functions - just the following:

     1.  AR reports (AR Transactions, AR outstanding, AR Aging) and user 
preferences - I know this can be done easily through the admin.pl menu
     2.  product search, price check (for "sellprice"only! not for other 
prices or functions in the product screen)
     3.  and most important, ALL ABOVE ONLY for customername= "Joes 
Deli", not any of the other accounts.

Items 2 and 3 are the tough ones for me.Which scripts would I need to 
modify and how?
