FWIW: depending on the type of aviation business you want to start, it's been my experience that most will start with a consulting firm that specializes in that type of operation set up. Most have former FAA people on staff and usually have a working relation with any required aviation attorneys. There is also FAA guidance on most of these processes that may provide an alternative path to follow. Good luck.Im looking for aviation attorney to help me start a new business , dealing with regulations and bureaucracy and in front of the FAA .
