(From fowlered34@gmail.com) Hello, 

I ran some SEO reporting tests on your website, and the results showed there are keywords you're using that search engines aren't able to pick up. Your website is most likely losing some points in possibly ranking high on search engine results. This is due to some issues that prevent Google and the other search engines to index your web pages better. 

For a cheap cost, I'll fix that for you. If you're interested, I'll give you a free consultation and show you how this will be achieved and show you the substantial benefit it can give to your business one you start getting more traffic (therefore generating more sales). I'd really like to help you out on your site, so please write back to inform me about when you're free for the consultation. Talk to you soon! 

Sincerely,
Ed Fowler
