Nowadays, there are plenty of resources to learn from. I highly suggest joining the Facebook page Grow My Cleaning Company. Mike Campion has created a wonderful community there, where we janitorial entrepreneurs can come, share our challenges, and get many responses to these challenges. Generally, people are very supportive on this page, and are often in the same shoes as us. I also took Mike's course, and he is a fantastic guy, with plenty of knowledge to share with people like us.
