Writing the sales letter myself was a great learning experience where I learned much more than paying and having it written for me.
The next route I took was to reister the product with ClickBank and it is now available for affiliates with a 75% commission rate. I thought it best to offer a 75% rate to try and attract affiliates.
I have created an 'affiliate' page on the site to make it easy for affiliates to get the hoplink code and my next task is to start driving traffic to both the sales letter and the affiliate page.
I will end with a big Thank you to everyone for all the help so far and to say that if you are in a fitness / bodybuilding niche that I would be incredibly grateful if you thought the product was worthy of you promoting it.
