Products and Services

We require a mechanism for service desk staff to just access and generate the following for customers:-

Create and amend Quotes – only amend the quotes they have created.
Only create quotes for a sub-set of the Products and Services, which have been set up with specific code prefix for example EG, EV, EY etc.
They should not be able to see any other Products or Services.

Are Price Lists a way of achieving this as we can just add the relevant Product & Services to a Price List for a set of Customers.
