Create an Access 2003 Database

I need someone to assist with the development of a database that captures several revenue streams. 1/2 of the information entered daily will come from SAP, but cannot interface due to SAP propriety. We can only print a report and enter the data. The other 1/2 of daily information is manually collected. All information gathered represents a source of revenue. I need the database to ultimately allow me to query revenue totals by day, by period, by week. The biggest key to the database is the ability to extract revenue by several periods of time. So I would imagine several queries would be necessary, but only a couple of tables and forms would be required. I would like to discuss the scope of the project over the phone to ensure there is a comfort level for both parties. I will happily pay the escrow upon a degree of satisfaction that I'm getting the database that will work.
