Business Listings in a .csv file

I need a list of businesses with the data coming from a website. The problem is that you can only get the business information by typing in an Australian postcode. Perhaps you have a way around this? The website will give you the name of the business and the address. If you can get the phone number, perhaps from a google search, that would be a plus. All results should be in a .csv file with a column for business name, business adress and phone number if available. I will give you the name of the website via private message. Please include the term megastock at the top of your private message. Success on this project will lead to other projects. Thanks
