(From grace.freeman925@gmail.com) Greetings!

I'm a freelance designer, and I sent you this message since I wanted to tell you about your website's potential to get you more sales. I can help you significantly improve your current website or rebuild you a new one from scratch, all for a cheap cost! Are you currently satisfied with how your website looks and functions? 

I can give you a call you and provide you with a free consultation if you have some spare time in the next few days. I also hope to give you some design ideas, get your feedback and give you a proposal. Please reply to let me know about the best time to reach out. I look forward to hearing back from you.
