Affordable training places for a traumatized rescue dog?

I adopted my dog, Carmy, a few months ago & have realized that he needs some professional training to help him with fearfulness, aggression towards men, excessive barking, etc. I was planning on doing private lessons with Every Dog, but I wont be able to get a consultation with them until next month. I was wondering if there are any other places in the area that may have sooner availability & work well with rescue dogs? Preferably something that’s more affordable. I don’t mind spending a couple hundred dollars if the training will help him, but I also don’t have $3,000 to spend on a 2 week board & train if that makes sense
