Equipment list in coded excel format

I am looking for a freelancer to create an equipment list in coded excel format for film equipment. Filmmakers that own film and production equipment (like expensive cameras and lenses) are required to furnish a list of the equipment to the insurance company. Furthermore, their equipment list may change periodically, so the list needs to be updated from time to time. My clients are not necessarily good at making the list the way we need it to be, so I have designed a very basic excel sheet that will make everyone happy. I want the excel spreadsheet to be manageable for the fields we need, but hard-coded so the user can't screw-up the template. I am attaching one sample template AND a sample of our company's stationary with color scheme and phone number and address etc... I would like some of my company's branding and color scheme on the final product. I will provide a basic template for the excel sheet. The list should include one simple formula. Ideal skills for this job include proficiency in excel and attention to detail. Please allow for edits to satisfaction thank you
