My Business Model Sucks! Suggest A Better One!

Okay basically it's been about 10 months since I've made my first affiliate website. I have made some money but currently only have two websites making me around a sale or two a week. My business model consists of a blog and reviews on physical items.
Since the two niches are quite large I will give them away.
One is on digital cameras (20 hits per day) and the other ...
On running equipment (120 hits per day)

I mainly write Ezine articles for traffic but sometimes get traffic from search engines. I love the writing part of the business and that's why I've actually started writing articles for other business owners.
However, the money only comes in when someone clicks through on one of my photo shopped images which says 'Buy Now' and they purchase.
The problem is I only get a click through rate ranging from 10-30% and then a conversion rate of 1-2%.
Obviously I could continue scaling this up but the amount of effort it takes to just get one site up is enough to be paid a good sum of money.

This is a well known business model but I just can't see it working long term for me as an individual. I'm thinking of moving to clickbank where I can make around £15 a sale.

What business model can I Implement that will be more effective at making sales than the one I currently have?

p.s. This isn't a rant to say how ineffective one method is, I just need to keep my options open and try other things.
