Need Microsoft Advisor
This is a community forum :-)
There are some Microsoft employees but most of the supporters including Moderators are "just" nice people from the community which came to help others. These community experts (which include Microsoft MVPs) are usually top experts and in most case they can provide the best solutions.
Does Microsoft offer a pro advisor in Teams to help small businesses set up Teams communications so that we could make outside calls
There is a service named
Advisor for Teams which can help you a lot. If this is what you are looking then you can get more information here:
If you mean a person to follow your businesses, then this is NOT something done free, except using community open discussion places like here in the forum. A limited help is given in different project like Microsoft Partners for example.
You can find free course at the Microsoft Lean site: https://learn.microsoft.com/en-us/learn/?WT.mc_id=DP-MVP-5001699
Another awesome place for Teams which you must check is the Teams support site. You can find recordings, tutorials and more Check it here: https://support.microsoft.com/en-us/teams
Usually when you need one-on-one support and if you do not have a support channel then as much as I know in most cases Microsoft point you to third party support.
If you need more information and options, then please try to be more focused on what exactly you want to get, do you look for free or paid support, and in what platform do you want t get it (in person, online community, online one-on-one and all you can provide)
