2 meetings simultaneously

I have read the requirements and they make no sense to me... 

We are a small business with less than 10 employees. 

Me and my partner usually run meetings with 1 client at a time. 

Sometimes I need to get on another meeting at the same time on the same laptop... 

Even with 2 seats in Zoom, this isnt possible. 
I end up using my phone for the 2nd meeting.
Which is not preferable since we do a LOT of screen sharing with clients. 

How can I run one meeting and then switch to a second meeting, similar to a zoom room? 

Is that the solution? Zoom rooms? 

Because the Business Plan is 10 seats minimum, which is a ridiculous requirement and jump from 2 users. 

Thanks!
