Hi Kris,
I see you are up to Expert 3 on the course. You should be able to do everything you need from just the beginner classes.

For the reservations, maybe Appointments might help.

If you have any specific issues, let us know, we'll try to help

Start here: Access Beginner 1

Kris, when you say "is there somebody who can help me with this?", if you're looking for someone to do it for you, you should post over on the paid AccessDev.NET forums. If you want to do it yourself, like Dan said start at the beginning.You'll go through all of this while learning.
