Hi,
my name is Esteban Salpeter and I'm an expert MS Access developer, with many years of experience on that platform. You can check out my portfolio to view some of my work.
Microsoft Access is a very friendly and powerfull tool to manage database driven apps.
It also has the flexibility to implement as a standalone desktop app, as well as a multiuser local network environment.
But if you prefer a 24/7 internet available app (to connect from home, office, with a pc, tablet or even your smart phone), maybe you can think of a webapp, with modern look and feel, friendly to general users.
Both alternatives can be done, since as I've observed in your attached excel, your data structure is quite simple (nevertheless calculations will be very accurate).
Do please take a look at my portfolio, since there you have both cases shown in printed screens.
Feel free to ask me any questions before contracting, I'll be glad to chat with you.
Hoping to start working together soon,
Best regards,
Esteban
