Talented ebook sales copy writers needed!!!

I'm looking for long-term relationship with good sales letter writer for my company. This sales letter is to be used to sell an ebook in mainly the internet marketing niche. It is a must that you have written sales letters for ebooks before. You must know how to research and have knowledge of the internet marketing niche to complete this project. All of my projects are mostly related to the internet marketing niche. I must see examples of similar work before I hire you. This product will be sold on Clickbank so it needs to be written in that sort of style. I will provide you an overview of the product and some example sites so you can have a good idea of what I'm selling. The sales letter must consist of the basics of a normal ebook sales letter. It must have a great heading and leadin. It must be a complete sales letter, from head line to P.S. Again, please show examples of previous work. I am looking for someone who has done this type of work before and is comfortable writing in this manner. You must have perfect English as well. I will retain all copyrights to the sales letter after payment. The sales letter should be between 1500 – 2000 words and formatted as if it were in HTML to show heading sizes and colors. The sales copy must pass premium copyscape. If the sales copy is written in bad English and doesn’t make sense you will not receive payment as you will have agreed to the terms I have set and you are a competent writer. You must be able to complete the project on time. Since this is the long-term project that I plan to launch around 3-5 products per month so the maximum budget I can pay is $40 USD per sales letter. The writer who provides the good quality of work will get continuous work. Thanks!
