Hi, there!
My name is Paris, and I was glad to see that you're looking for an Excel developer. According to your brief, you want to have an Excel application to merge data from 100 Excel sheets to a new Excel template. I plan to use a combination of formulas and VBA code to accomplish this. I need some clarification before proceeding if you don't mind. I will charge you $450 and can deliver within a week (a single milestone to release once you're satisfied with the final result).
I'm among the most experienced, and skilled Excel, and VBA developers on this platform. I have completed over 295 projects successfully in six years, and I feel confident in achieving your task as well. You're welcome to visit my page (https://www.freelancer.com/u/paris2785) and get an idea of who I am and what services I provide to my clients.
I'm online from 8 am to 9 pm, Athens time (including weekends).
I'm looking forward to working with you.
Sincerely,
Paris Pallas
