MS Access Database fixing and UI enhancement

Hi Guys, I am looking for someone with excellent MS Access and UI design skills. I have built a very small software to manage the sales of used winter stuffs. This is a charity event which will help less fortunate people to have the chance to practice winter sport like others. I found the template from Northwind database sample and adapted it to my needs. Unfortunately, I need some one to fix the last bugs with the VBA and SQL codes and slightly enhance the UI. The Deadline is on the 16th of September. After a brief interview to give you the database and information required, The project will cover the following things: 1. Secure application. Only administrator can unlock the code and database. 2. Develop/Modify Step 1 i.e. Registering the Supplier and the Items he/she is offering. 3. Develop/Modify Step 2 i.e. Registering the Customer and the invoicing of the customer. 4. Develop/Modify Step 3 a) i.e. Payment to the Supplier. 5. Develop/Modify Step 3 b) i.e. Item Return to the Supplier. 6. Develop/Modify the Reports.
