I need a Sales Business Letter Written

I need a business sales letter written. The sales letter is about a new automotive finance program that is being rolled out that I will be selling. Winning freelancer will receive all of the marketing materials that I have so far. There is no word limit, or minimum word count, I would like for the sales letter to be able to fit on one page when formatted into a business letter format. The sales letter will need to include my email address, my phone number, and a website address for the reader to go to to find out more information. All of that information will be provided to the winning bitter as well.
