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 where a drop-down list's options will be dependent on the selection made on another drop-down list. I completed a similar project, not more than a month ago, and I know exactly how to deal with it.
I'm among the most experienced, and skilled Excel, and VBA developers on this platform. I have completed over 290 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 $180 and can deliver within three 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
