In addtition to the awesome comments and yes you do great work. Perhaps it's time to think about doing an end around. That's an old football term from years ago as a high school QB. Things I've come to know is that Branding may not be the issue. Time could be the factor. Pick a path, and continue to share your services through those like minded people that you already work with such as Schools, Families, Local Non-profits, other business assocaiations. ect. (Groups already mentioned). Think of yourself as a farmer. You don't get to plant a great seed one day and harvest in a week. This process as you know, take Tiiiimmmmmmmmmmeeeeee. 

Over time, I found out about other industries such as Tourism and the Convention Business. That's a whole new world of possibilities. Imagine being at an event with 200 - 500 attendees where each one is a potential prospect for more convention business and as a default, Portraits, Wedding, Students, and the kind of images you never thought you would be photographing. Like, in my case, construction documentation. 

The brand is not the images but the person producing the images. We are the Brand. People are choosing us because of how we make them feel when we are in their presence.  And we do great work as the added bonus. Maybe it's as simple as continuing to demonstrate how much you love what you do. Clients can feel that energy sometimes more than a cool layout. Be flexible.

One of my mentors always reminds us that if you're in business and not making a profit, you're going out of business.
