Copywriting 1page/500 Word for my web design company

I need to have content for my website's services page. Basically, this is a web design service company and I offer custom web design, ecommerce, and corporate identity (basically graphics for marketing materials such as business cards, logos, etc). I want it to be short and simple. I noticed that a lot of people don't read these sections because my customers already who we are and what we do already. So rather than write about what services we offer, I rather talk about how we are different from the rest of the competition. This way, it's short and gets the message across. 500 words is the max I want to have.
