4462 sales letter needed

I need a direct sales letter written for an upcoming product. The sales letter needs to be very professional, informative, and obviously spark intrest in potential customers. I expect 100% perfect english, if english is not your native language, or you are not extremely positive you can write with perfect grammar, please do not bid on this project. I would prefer someone with experience in writing sales letters, and I will require examples of your work before I choose you for this project. For example, pasting a short sales letter you have written in the PMB may be an excellent way to get this project. The sales letter should be completed within 3 hrs. As for the details of the product which you are to be writing about, they will be provided after via PMB.
