Lookin for Samsung/Google Calendar Guru

Looking for someone who really knows their way around Samsung Google Calendar set up and syncing. Examples of what we're looking for:

-Getting Google Calendar synced back as far as possible

-Figure out how to text/share calendar stops with multiple people at once (right now we can only do individually)

-Other small fixes/tips to run smoothly between devices.

Paying $100/hr for someone who can help get this working correctly. Please message with experience & availability.
