Excel Spreadsheet Frontend

I have a rate quoting spreadsheet that I want to distrubute. I would like to create a front end to the spreadsheet that will interface with it but keep my spreadsheet hidden and uneditable. Also, I will want a serial number built to have the frontend disable itself after a specified time to prevent people from using it past a date to prevent old rates being quoted. I will require a serial generator to produce the new serial numbers. It would be very helpful if the serial generator was written using Excel or a program that can be run from my Pocket PC. If the generator is made with Excel, it must be able to be used with Pocket versions of Excel. There are several reports, and options that will be required for input and export, as well as a method of adding, changing, or editing; rates, benefits and companies that will be used in the spreadsheet. ## 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 and hopefully a Pocket PC 2002 version. ## Deadline information Prior to submitting a complete bid, it might be helpful to see the spreadsheet and the data contained in it. I will be working on several screen shots and uploading them to [login to view URL] I might ask that the persons I narrow the bidding down to be able to demonstrate there ability in this task by using some of my data and make a simple interface to produce one rate. I'm not asking for a lot only a VERY SIMPLE illistration, this way you may also get more of a feel for the actual project.
