Hi, there!
My name is Paris, and I was glad to see that you're looking for an Access developer. According to your brief, you want to have an Access database upgraded and make it multi-user.
I will charge you $200 and can deliver within five days (a single milestone to release once you're satisfied with the final result).
I'm among the most experienced, and skilled Access, 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'm online from 8 am to 9 pm, Athens time (including weekends).
I'm looking forward to working with you.
Sincerely,
Paris Pallas
