(From freestoneed@gmail.com) Hi! 

I am a specialist in search engine optimization, and I noticed that you could use some help with your rankings in web searches like Google. Having your business come up on the first page of search results when potential clients are looking for products/services online is essential to making your website more profitable.

My services are reasonably priced so that even the smallest businesses consider them cheap. If you're interested, I'd be happy to give you a free consultation over the phone to show you where you stand now and what can be done to improve your ranking in the search results. Please let me know the best time to call. Talk to you soon!`


Best regards,
Ed Freestone
