Website sales letter

I am a home based business selling information DVD's. I use classified ads in the papers to drive traffic to my website where customers can read my sales letter, buy the product, and I ship the DVD's to them anywhere in the U.K. The products I have to sell at the moment are 3 DVD's of presentations at the World Internet Summit. Two of the DVD's are presentations of internet marketing techniques and how to make money with the internet. The third DVD' was one I wanted to give away as a bonus, it takes you through step by step and shows you how to build a website from scratch.

I am looking for someone to write the sales letter for the website. I want the equivalent of at least a four page letter. Everything else is ready to go so the sooner the better for completion.

I am also looking for someone who is interested in taking 5% of all sales made as payment. This is a starting product which I am selling for £67. I have 10 more products ready to go which will retail for £400 each, and five products for £5000 each. Each of these products, which are all information products, will need sales letters and if the initial sales letter works, I am happy to keep the 5% commision of all sales for the other products. The better your sales letter is, the more money we will both make.
