Access Database creation

I have a database of sales that I have created in Excel which is growing becoming too big and unwieldy. It needs converting to Access with a series of intuitive windows for entering data, avoiding duplications and extracting reports. I did already ask for bids of conversion from Excel to Access but more is required than simple conversion. I am looking for a bespoke and easy to use data entering system that is obvious to use. Please let me know what more info you would require to bid. Thank you. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows 2000
