Set up some sort of online, or even better, night course at a local college.
Charge for it.
By teaching, you set yourself up as an authority on the subject. The more you teach, the more people see you as the person who knows those most on the subject.
What you'll get out of it is more business referrals and more clients.
Seems weird, and most people will say "you'll be training your competition!" but in fact, you won't.
Just because you teach someone how to use a camera, it doesn't turn them into a professional photographer, but it does form a relationship of trust and knowledge between you and boatloads of potential clients.
One that my wife likes taking advantage of... and which makes the photographers a huge load of money is the following.
Groupon/Living social £20 deals for a photo shoot and a single photo. When you get there you are shown some "upgraded options" you can choose from.
Once the shoot is done you have to book an appointment to come back to choose your free photo (this has to be in person and cannot be online). When you are there they put you in a theatre of sorts, dim the lights and put on some emotional "city of angels" type music, show you a slideshow of photos and then say "which one of these beautiful photos would you like".
Let me tell you. This is a powerful business model that can make a ton of cash if done right.
