No need to put a comma in the logo.
I'm not too hung up on making something out of my initials, although I am liking a few I'm seeing already.
What I might light to see also is a square where my name is in white and the square behind it is a color, with some block lettering. Maybe put a small icon bottom right of the square. I'm also open to something that has nothing to do with law or the letters of my name -- like an animal, or an object (not a gavel or scales or column or anything "law" related)--maybe a bridge or a key or a lantern or anything else that symbolizes strength, wisdom, acumen etc
We are also a border city--Augusta, Georgia. We are on a river, that separates South Carolina from Georgia. I'm open to something that incorporates a river, since I practice law in both states. Unfortunately, we don't have an iconic bridge that goes across the Savannah River here, unlike Savannah, GA. Hunter Maclean in Savannah uses something to incorporate that bridge (https://www.huntermaclean.com/)
I'm also open to focusing just on the "Jackson" and having "M. Austin" and "Attorney at Law" (and LLC) downplayed a bit in the logo
Law firm logos that you can't go wrong emulating:
...they are all a lot alike, but they are clean and easy to recognize. It would be nice to be able to actually put a logo on some clothing/swag and have people WANT to wear it. So a simple clean logo, not just my name would be nice. Here's the vault's top 100 firms and their logos are all right there: http://www.vault.com/company-rankin…w-100?pg=9
