I had a wonderful attorney that would have probably done an outstanding job with this, but like us, he got to that point that it weren't fun no more. Still a wonderful guy, but not practicing anymore. My most recent encounter with an attorney ended up with far less than stellar results. I wrote a long letter about how he should NOT try to do his secretaries job. He sent me a file to review and sign. It had the Thomson Reuter's header embedded in the inline document in an e-mail. I separated the file out of the e-mail and with some effort removed the headers and sent it back. That was only one of many very disappointing steps in a long process. I finally fired him over the phone with a voice message. I would love to share the e-mail response I got from him. Run on sentences. Sentences starting with BUT and AND ....  very embarrassing, but definitive confirmation that getting rid of this waste of space was a good choice.  Afterward I sat down with the other party and reached an equitable settlement.

Years (decades?) ago I had a good (although costly) experience  with https://tatp.com/  I worked with Daniel Trump and Bruce Prescott They may be a good fit for this.
