Help with Google Drive and G Mail

I have bought a new MacBook Air and I'm having trouble setting up Google Mail. Some of it works but some of it doesn't also, I want to store folders and files on the computer not just in the drive and I don't know how to do that.
I would like someone to join me in a Google meet and explain how to solve these problems, it's a matter of the right settings I think rather than anything very technical.
I estimate one hour would be enough, but if not then we can agree to more time if necessary. My budget is £45 for the hour.
This is my second attempt at this project, I appointed someone first time round but they were not helpful.


Thanks, James
