Well when you state 'anything over $2,000' it seems as though $2000 is around your average selling price. Hardly high calibre.
Anyone can wash, film, photograph and edit selling ads. Anyone. The art of the selling when you sell on behalf of someone is not just making the ad but who you are yourself and how much exposure YOU can give the horse.
Not on Dreamhorse. Not on EquineNow. You, yourself generating additional interest on top of what someone can do themselves. What you have decribed is not a special service, just a willingness to do the work that someone else doesn't want to do.
So to me charging $30 per showing is absurd for a horse that is under $5,000 but hey a sucker is born every minute.
You'd think it was that easy wouldn't you... But let's admit it, a large number of sales ads have photos which won't appeal to those experienced, serious shoppers.
For instance, how many people do we get posting in the conformation thread with really awkward photos? Those are often the photos offered up, especially on sites with free ads. They are useless if conformation is important because I'm looking for my next show horse, breeding stock, etc. Less important if all I want is a sound, sane partner for my kids to plod around the yard on.
I would probably happily pay someone money to do the prep and phtography on a horse I was trying to promote for any reason. Not because I can't do it, but because I have enough on my plate without having to worry about getting those perfect shots... Bathing, braiding and all.
I have been asked if I would shoot promo shots for people, though I always ask that they have the horse appropriately turned out, and the hander or rider as well... I just don't have that much spare time on my hands to do the part anyone with a hose and shampoo bottle can do.
I have been paid $60 per shoot. They will get 20-25 finished shots (cropped, high resolution, on a disc or memory stick). Generally I will shoot anywhere between 100 and 200 photos per shoot. The clients I've had have also then taken their favorites and blown them up for framing as a memoir. I am far from a "professional" photographer, but I've been told I have a good eye for capturing great moments.
I do think there may be a niche for this sort if thing... But what you charge may be better as a sliding scale rather than a set price. I actually didn't set my price, it was offered to me, then passed along as word of mouth. I have no. Idea what they were selling their horse's for, price wise... Nor did I care, I wanted the chance to practice my skills, with the lunch I was fed and the fun we had on top of the cash, I was more than happy LOL
