(From nicholasmorgan32@outlook.com) Greetings!

I'm a freelance web designer, and I deliver excellent results for a cheap price and can guarantee that you're getting the most out of my services. Would you be interested in making upgrades on your website, or possibly rebuilding it completely into something more stunning and highly functional to suit your business needs? 

If you are, then I'd like to send you a portfolio of some of my previous work so you can have an idea of what I can do for you for an affordable price. Let me know what questions you have and what you're looking to do with the site, so I can provide you with a free consultation via a phone call and hopefully a proposal. Talk to you soon! 

Nicholas Morgan
