(From edingram151@gmail.com) Hello!

I'm freelance search engine optimization specialist currently looking for new clients who need SEO services but are on a budget. I was just looking at your site and wanted to let you know that I can get you more site visits, which eventually leads to getting more profit. I've helped dozens of other websites owned by small businesses and I can show you case studies for what it's done for their business. You'll be surprised of how much it boosted their profits.

Please reply to let me know if you're interested in my services so we can schedule a free consultation. All of the info I'll hand over can be useful whether or not you choose to avail of my services. I hope to speak with you soon.

Best regards,
Ed Ingram
