Gather Email Addresses for Foodservice Distributors

We manufacture a variety of healthy products that use the all natural ingredient Xylitol. We are trying to compile an email only list of all the FoodService Distributors in the United States. A food Service distributor is a company that sells goods, food items to restaurants, schools, hotels, offices, etc. They don't sell to stores, they sell to places where food is served. We want a freshly compiled list of the emails for all these companies. Initial bids should have a small sampling of email addresses so we can see the quality make sure the project is understoond.
