Two indoor ranges that offer weekly classes around New Orleans are St Bernard Indoor Shooting Center in Arabi (Saturdays or Sundays 8:30-6:30) and the Shooter's Club in Harahan (every Saturday 11-8).
If you have a group of people, you can also do a private lesson with Dave Newman of Concealed Carry Nola. Could be worthwhile and fun to do a private class with your buddies, and the price is almost the same. I did mine with Dave and he's no BS.
I did my original with Dave Newman as well as my renewal. I would recommend him.
