(From edfrez.478@gmail.com) Greetings!

I'm an expert with all the different programming languages, website platforms, shopping carts; and my expertise is in the WordPress website platform (I'd love to tell you more info about this if you're not familiar). Have you thought of making some upgrades on your website or building a new one? If so then I'd like to speak with you. I've been creating and both beautiful and efficient websites for over a decade now and I'm a professional at what I do. 

I do both programming and design work for a cheap price that even small businesses can afford. I also guarantee you that I do all the web design work by myself freelance, and I never outsource. If you'd like to know more, I'll send you my portfolio and some more detailed information about my services, then we can schedule a time for us to talk. Please write back to let me know. Talk soon!

Thank you,
Edward Frez | Web Designer / Developer
