windows based simple expenses tracking program

I am looking for a programmer to develop a custom lawn service bookkeeping program to run on a Windows operating system. The primary data to be tracked are expenses, however, the data should ideally be exportable in case I need to access it further down the line. The program should have all the basic bookkeeping features such as tracking sales, invoices and expenses, but should also provide an export feature if needed. I need a program for In The Beginning Lawn Services that include: 1) Customer Name. 2) Address. 3) Description of the property. 4) The date that the service is to take place. 5) The date that the service actually took place. 6) Add two weeks to the date of the actual service date. 7) How much they are being charged. 8) Charge them when the actual work has been done. 9) How much they paid along with the date they paid. 10) The balance.
