Advertising / Sales / Marketing Letter Needed

I need an ad writer or advertising / sales / marketing expert for the following: A professional written letter (full page 8 1/2 x 11) with design to sell a website to potentials clients. My target market is new entrepreneurs, small and medium-sized businesses. We know, there are thousands of website companies out there, so we need to be the one that stands out. What would inspire a business owner to redesign his existing site? What would inspire an entrepreneur to come to us for his website to be developed? Why us? That's your job, to inspire someone to choose us other than our competition. If the client already has an existing website, I want them to upgrade to what I'm offering. The advertising will be used as an insert in a small local advertising print magazine. I will provide more details upon request. SAMPLES MUST BE PROVIDED.
