What is the best way to find an attorney to close out two businesses

I'm not sure what you mean by "the best way to find a lawyer." What I can tell you is that you need to file a Notice of Winding Up on the Missouri Secretary of State (SOS) website. That puts folks on notice that you are closing down the business. Once things are fully shut down, you file Articles of Termination with the SOS website. To ensure you receive the most protection from creditors coming after the business later on, you will want to publish the Notice of Winding Up with two different publications, listing the name and address of where such creditors can make claims. If you do that after the timeframe expires, those creditors cannot pursue a claim. It's not a terribly difficult process, but it does need to be followed correctly to ensure nothing comes back to cause problems later. I recommend contacting a business attorney to ensure that everything is handled correctly. Good luck.
