Do have small round wood table tops...like raw wood

Check website

Yes the do...

I haven't seen it at this location

I don't recall ever seeing any. There are tons of people that do woodworking projects like this in their garage. Look on Facebook marketplace for Picnic tables and you will find the folks that can build this for you. The picnic tables are usually less than a $100 so something like this would probably be cheaper. Good luck!

Yes, look in Lawn and Garden
