How to sell photography - What would be the best way to try and sell my Photography business?

Best Ways To Make Money Selling Photography:

I have large photography business in a small NSW town. Main areas of work are Weddings, Portraits, School photos, commercial and retail shop.

Try The Rangefinder Magazine classified section.
I would make up a flyer or postcard or something like that. Send them to all the photographers with a 100 mile radius of you. I'm sure you'll find someone that is looking to gain some additional equipment, and gain from your marketing. Make sure to tell them they can keep your business number. That way anyone trying to contact your business can be automatically forwarded to them. IMO that's a big selling point.
