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 check if a motel management/reservations/point of sale environment is a feasible solution in Excel. If I were you, I would go with a database such as MS Access. It's a robust and cheap solution, and it will serve you well. Let me know if you'd be interested in such a database.
I'm among the most experienced, and skilled Access, Excel and VBA developers on this platform. I have completed 269 projects successfully in less than six years, and I feel confident to complete your project as well. You're welcome to visit my page on this platform (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
