My apologies on the delay, I was offline and was not able to respond. Let me reply to each question as posted below.
Did the buyer act illegally......
Acting 'illegally' means in violation of criminal law. For him to act illegally he must violate something from the criminal code. Based on his actions, he is potentially misleading you and was attempting to defraud you, but that is not likely something that the state would consider 'criminal', as most would see it as a civil matter, specifically a contractual dispute. You can argue that the criminal element is that he was using your identity and information without your consent or permission (identity theft), and potentially contact the state to see if the licensing board could investigate him for his actions.
are his actions actionable in criminal court/ civil court and to what degree ......
Criminal is not likely based on the facts I explained above. That is not to say his actions do not have a criminal element, but I suspect the state won't elect to pursue charges. Civilly you have damages for breach of contract, bad faith, fraud, and conversion. Likewise you can also potentially file for a UCC-1 claim against the business and seek a lien even if he is able to somehow transfer this under his name.
is there a way to recover my lost monies or stop him from taking my business from me without payment?
Yes, the UCC-1 filing, and simply a suit against him can help. You can request the courts for the right to file for an injunction against the business so that it cannot be sold, dissolved, or otherwise utilized until the suit is resolved in one way or in an another.
Are you ever going to be able to answer these questions or am I being billed for you to continue to ask me questions?
I just answered your questions, I hope-should you have more questions I will be happy to clarify. You are not billed until you choose to positively rate my response.
Will you be able to give me some direction?
Absolutely, and I am glad to do so.
