Listen, I commend you on constantly trying. That work ethic will take you far once you hit your stride. You're in the unique situation of being an owner operator. Compete where other's can't and market that. Not some stock pic from Getty images. I get an overwhelming response from people that see my wife and kids on my marketing materials. People love supporting local people with families they can relate too. Make some fliers using your wife and kids. If you don't have any kids, go buy a puppy.
I never wanted to use pics of my family, but my former assistant was insistent I do it. I'm glad I did.
Just yesterday I was told by a lady she felt safe with me coming to her home. She had watched my YouTube channel, read my google and yelp reviews, and had seen my pictures online. She said the last time she had her carpets cleaned was by Stinky Steamer and the guy looked like a rapist. She said she was nervous the entire time he was there.
So, be clean cut, take a good picture, and whore out your family on your marketing material.
