I would like you to meet Michael McBride, an attorney from Ohio that does what you want to do. He is a dedicated Third Wave lawyer and a practitioner of the art.
Too often, I think, I talk to people, or get emails from attorneys, that simply say that my case is unusual, but that you cannot work without office space and staff and the trappings of the Second Wave or traditional practice of law. But you can, and the resistance is between your two ears.
I think what Michael McBride says is very compelling. In regard to a recent post, this is what he wrote:
I have been in private practice over 20 years; 18 of them in an office setting. The last 2 years, I shed the brick and mortar and its overhead...and I say, "Why did I not do this before!" I meet and greet clients at places with Wi-Fi with my laptop and most if not all have e-communications set up for transfer of .pdf's. It has worked well so far. If you need to meet, I do what you do: Panera or Starbucks; local bar associations usually have places for free. No one has ever complained as I meet at the convenience of my clients which they really appreciate. There is always a work around to any obstacle.
