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 application in Excel that will bring selected data from separate spreadsheets into a master Excel sheet. I'm going to use a combination of formulas and VBA code for this.
I'm among the most experienced, and skilled Excel, and VBA developers on this platform. I have completed over 270 projects successfully in less than six years, and I feel confident to complete your project 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 will charge you $120 and can deliver within a couple of days (a single milestone to release once you're satisfied with the final result).
I'm online from 8 am to 9 pm, Athens time (including weekends).
I'm looking forward to working with you.
Sincerely,
Paris Pallas
