Web Design Ecoomerce

We need to someone to build a 10 page website that has the following: 1. Directory (yellow pages) that can be updated easily by us. 2. A help wanted section that can be updated easily by us. 3. An ecommerce section that can be updated easily by us. 4. A news/ evennts section that can be updated easily by us. The designer would have to keep in mind that the site should be easily navigational for the 50 + demographic with the capability of changing the size of the fonts through out the site.
