Examine a VB, Excel and Access Program

We have found a small Invoice (accounting) application built using Excel, Access & VB. We would like to modify the application to add some new features and functions. It uses Microsoft Access to store the data, Excel for the user interface (UI) and reports and Visual Basic to create simple forms and menus. I would like to find an experienced programmer (with VB, Access and Excel skills) that can look at the documentation, workbooks, code, macros and forms and tell us if this application can be further customized. We want to add new reports in the Excel worksheets, and add some new VB forms for data entry. Please note - this is research only. There is no programming involved at this time. This should only take and hour or two. I will provide the program documentation to the selected programmer and we will then discuss your findings on Yahoo Messenger. The program uses a COM add-in program to support communication between the Access Database and the Excel front-end. The application developer has provided the user some ability to customize the appearance of the screens and reports. He has also recently added the ability to customize the database backend. We do not want to clone the application; we just want to modify it. [Please bid $27 - I still have that remaining in my account.]
