Convert Excel spreadsheet to VBA GUI

I have an EXCEL spreadsheet that allows you enter costs for a product. Spreadsheet is attached. You should have enough expertise with profit margin calculations and EXCEL to understand the current formulas and what the spreadsheet is doing. If you can't understand every aspect of the current spreadsheet DON'T BID. I will not answer your questions. You aren't experienced enough. You must explain in the private message board your understaning of our requirements. If you do not explain what you are REQUIRED to do then how do I know you understand what we need. You also have to explain your expertise with VBA, EXCEL, Macros and GUI DESIGN. In some cases the costs are in two sections. Each section is the related costs for a feature. So there are two features and the related costs. Some products only have one feature and therefore on set of costs. The spreadsheet allows the user to apply different markup percentage rates to the costs to determine what the sales price would be for the product based on the markup values. There are 3 other cost recovery percentage entries that are applied. Profit is calculated and profit margin. Using a discount percentage a reseller price is also determined. An associated business receives a percentage of gross sales. This amount is also calculated based on the sales price. The spreadsheet is setup for 6 markup scenarios that you can see in the spreadsheet all at once. The spreadsheet also has a macro that enable you to hide the scenario(s) you don't want displayed. The spreadsheet is setup with all the cells visible. The requirements of the project is to use VBA to create a very user friendly, more aesthetically pleasing GUI for non-experienced EXCEL users to enter well labelled data inputs, variables, and a more visually appealing display of results. It looks too complicated with all the spreadsheet cell and data values displaying. It also needs to be user proof so that they can't accidently delete cell formulas, make an entry in the cell where no entry is permitted and it has to look very professional, an appropriate use of colours to help identify sections, clever ways to hide scenarios the user does not want to see and is very intuitive and easy to use. The other requirement is a reverse calculation. Currently costs and markups are entered to determine a profit margin. We would like to enter costs and desired profit margin to determine all the other values e.g. sales price. 100% milestone will not be considered. Lowest bidder will have an advantage in getting the project.
