Multiple Values Wordpress Custom Fields

So i had a client who needed to enter into their site a list of the manufactures that they sell in their store. In the past, i have set up a category called "Manufacturers" and then told them to create a new post for each one. The following client, just wanted the manufacturer name, logo, and website. So i created 1 wordpress page called "manufacturers" and created a custom field on that page called "manufacturer info."
