(From freestoneed@gmail.com) Hello,

Are you currently pleased with the number of sales your website is able to make? Is it getting enough visits from potential clients?I'm a freelance SEO specialist and I saw the potential of your website. I'm offering to help you boost the amount of traffic generated by your site so you can get more sales.

If you'd like, I'll send you case studies from my previous work, so you can have an idea of what it's like before and after a website has been optimized for web searches. My services come at a cheap price that even small businesses can afford them. Please reply let me know if you're interested. Talk to you soon!

Best regards,
Ed Freestone
