HVAC Contractor Investment Opportunity

Hi, I am currently negotiating terms with two HVAC contracting companies. I may be looking for outside investors in the near future, depending on the terms. If you want me to keep you in the loop, please let me know.
The companies have been in business over ten years, have a team in place, and they are very profitable. No broker involved. My background includes roughly 20 years of sales and marketing in the HVAC space.
