Create a Marketing Agency Program and document it

Hello, I am interested in developing a Marketing agency program as per the enclosed. I have arranged for the use case diagram and would like the Record promotion cost use case to be developed. The developer needs to consider an architecture style and arrange 2 design patterns while designing the program and document the reasons they were chosen. Consistent test data must be provided, with unit testings applied and documented via JUnit4 and case testing. A domain class diagram is enclosed which needs to be modified as an implementation model for the Use case above. Deadline to be 09/01/14 9pm UK time. Any further questions let me know.
