Hi there - My name is Paris.
I've read your brief and can see that you'd like to have an Excel spreadsheet. I have 7 years’ experience designing and developing Excel spreadsheets. I would approach your project by creating a draft spreadsheet and send it to you for review. I am highly qualified for this project and would love to speak with you further about taking this project on. If you'd like to view my previous work, as well as feedback, take a look at my Freelancer Portfolio (https://www.freelancer.com/u/paris2785.html).
