Hey,
I'm sorry, I have totally ignored some things from the description but that's because I believe in your idea of selling the important few things that are hard to get. So in such products the marketing competition is easy to beat. I have this offer, a package basically, that I am 100% confident will take your sales to a high level. I am planning to write 50 articles with remarkable SEO. I have a senior SEO specialist with me, he's been doing this for 12 and more years. These articles will be power packed to focus only and only those people who are specifically searching for the products you guys are working on, 3 months after uploading the content, you will notice a dramatic rise in your sales. Let me know if you're interested. For the $500 you will get all the articles, keyword researches and SEO incorporation.
Cheers!
Nayab Khawar
