We want to move our from Google Cloud and need some one to move all our files to the new hosting

We have not had a good experience with Google cloud and we need help to be able to get copies and back up of all our files and move them to our new host that will be Justhost.
Also have to set up again our e mails from our web page.
Our web page is: www.alvalley.com

And our e mails that are not working are all those ending in : alvalley.com
