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 updated so that it doesn't need a USB stick to operate. Moreover, I will add a pop-up form to enter a long password. If the password is valid the app will open, otherwise, it will close.
I'm among the most experienced, and skilled Excel, and VBA developers on this platform. I have completed over 280 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 will charge you $400 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
