Did you do Howard's suggestion of running grant command? It seems the installation is failing based on that.
How are you creating the MySQL moodle database? Can you use PHPMyAdmin tool to create the database and grant access to the moodle user account? Make sure that you select 'UTF8' as the default character set since that's the recommendation. Finally, make sure to not have CAPS lock on when creating username and password as MySQL uses case sensitive username and passwords.
Did you reach out Total Choice Hosting support? Sometimes they can assist you faster that way.
