add a page to a website with admin

i would like someone to help me to? add a webpage to a foodlovers website that allows users to get more detail about a restaurant. also the admin console needs to allow the admin to easily update this page.? this page? will include basic restaurant information, some menu and dish information, some user comment/rating information, some pix and videos, and some special promotion info. also i would like users to be able to? add comments, and to sign up for email list and twitter. the website is [[login to view URL]][1] if u would like to take a look at the look and feel. i have a rough mock-up of this restaurant detail page, but the final disign will be different so the developer needs to have some artistry. thx
