Hi,
I have a book about Copywriting and you can get the pdf version for free, review it, and if you like it send me a testimonial (with photo and website url if you want)...
The book will teach you how to write a salesletter from scratch - there's a 10 step template you just follow it step by step, you'll be able to write a salesletter regardless what product or service you're trying to sell.
Reply here or via pm if you're interested, I'll send you the ebook immediately.
Thanks
