Compile the necessary documents and, if necessary, seek further advice from an expert. Perhaps there’s someone in your circle of acquaintances? Maybe your tax consultant can help you.

Otherwise, contact the Chamber of Commerce responsible for your city (https://www.uschamber.com/co/chambers) and arrange a consultation appointment.

Then submit the documents, i.e., register your business in the desired legal form.
