Starting hidden excel instances

As I have developped a software working on Excel, but when the final user uses it he has not to know it works on Excel nor to see the Excel sheets, but he has to see only a couble of prompts already included in the developped program, I need hire a programmer to write another program to open and close hidden instances of Excel, prompting only the prompts already included in the developped Excel program.? I will also need installation code that can hide/encrypt the excel file and keep it hidden from task manager, require the user to install the Web Components if missing on its pc and set automatically the Excel options as needed, before the program become available to user. This installation program has to allow me to set it up in an easy manner as? each month I have to prepare different files with that excel program. I whan to know if you are able to develop such a short program and in positive case at what cost and time. ## Deliverables When I said? ? I need only the installation program for a software already developped by me in excel I forgot to say that I need also a piece of software to set the installation software, because it has to be used by users not by me.
