I need a UML Model created for the following scenario.

Bobby Bearcat wanted to capitalize on the recent success of the Universitys athletic teams. He has decided to purchase and market memorabilia that will appeal to Bearcat fans under the name Bearcat Paws. The memorabilia include embroidered Bearcat paws in various sizes and colors, football helmets in various sizes, and basketballs in various sizes. Each type of memorabilia has a unique identification number. Bobby has identified a number of potential vendors to supply these memorabilia and requires the vendor to submit a price quote before any purchases are made from the vendor. The vendors are able to provide price quotes on more than one type of memorabilia. Vendors are not assigned to specific purchase agents. An individual purchase of memorabilia can consist of multiple inventory types.

All purchases are paid for with a check drawn on a single account. Bearcat Paws has several accounts that can be used to pay for purchases. Individual payments are processed by a single accounts payable clerk who takes advantage of normal discount and payment terms. No partial payments are made, but a given payment could be made for multiple purchases from the same vendor.

Bearcat Paws markets its products to potential customers with an internet site. Once the order is submitted by the customer it is processed by a single sales clerk. Customer payments are submitted online using a credit card. The credit card receipts are processed for deposit to a single bank account by a single cashier.

Employees are added to the database on the day they are hired. You should model the classes of employees as separate entities.
