And... treat it like a business. Show up on time. Answer your phone/text/emails. If you need to cancel, give notice.
I'm continually flummoxed at how generally bad service industries are in many areas. We had one guy cutting our lawn. BEST EVER. Younger kid - showed up on time, notified ahead when he was coming, would notify if he couldn't make it re: weather delays, then would give us updated time/date. Even more "professional" than professional services we've used. We had one good year, then "I'm going to college, and can't do this any more". He could probably earn more expanding out his operation than he will from whatever college degree he will get. :(
