u/RichRollersPainting

I am 26 years old and i have a 9-5 job. I recently started my own business as a painting contractor. In order to be more efficient and organized with my business, I created a CRM (customer relationship management) system and converted it into an app to help other contractors and tradesman. Does anyone have any advice on how to market something like this? Its hard with Facebook groups because they all have restrictions.
