I can tell you what most millionaires do (backed by research). They will go to a specialized accountant/attorney. If you are serious and ready to pull the trigger, finding and retaining a knowledgeable accountant and attorney in your specialized field pays for itself very quickly. I will not quote the location, but in the best selling book "The Millionaire Next Door", the wealthy do not cut corners when it comes to tax and legal advice. THEY JUST DO NOT!! So, if you are really serious, spend the $500.-$2,000. for half hour-hour talks with both for the set up. Afterwords, you can use cheaper accountant/attorney (who are still in the field).
