Data mining for US retailer store addresses

We are looking to populate our database with a list of U.S. retail store chains. As an experiment we would like to see how simple or difficult it is for someone to deliver the following: - ALL US retail stores for the following retailers: The Gap, Banana Republic, Jos A Bank, and The Container Store. (Note: there are several hundred Gap, Banana Republic, and Jos A Bank stores) - We need the following for each store: store name, address, city, state, zip, telephone. - Delivered in Excel spreadsheet. I imagine there are numerous methods for getting this data. We are looking to work with someone who is efficient, timely and accurate. Data would be double checked to ensure accuracy. If this project goes well, we would likely want to continue with collecting data on other chain store retailers. Please let me know if there are any questions.
