Martine, check these people out, I do not know them personally but they may do and have what you are looking for - http://www.kennesawglass.com/glass-table-top.html
Michael Cole.. over 20yrs in the business. 770.597.0766 or firstname.lastname@example.org He is an independent and priced very well. If you want the "storefront" .. Binswanger Glass is all over Atlanta too.
Check out your local auto glass stores as well. They normally cut glass for tables and windows.
Try "Any Glass". They have all kinds of options and edges.
Also, Diamond Glass in Alpharetta gets around alot.
I miss Buckhead Glass too, they were a good restoration (wavy) glass source.
1550 Beaver Ruin Road
Did a great job and fast turn around time, even during the holidays.
thanks again! I've been speaking to Drexler Glass. They seem professional and on top of it there.
