Research and Data Base

I need to have an Excel spreadsheet with names, email and city of all the coffee shops in Colorado. I want to exclude any chain coffee shops like Starbucks. I want someone who will do the deep digging in several sources (chambers, yellow pages, google, etc.) to find these coffee shops - I anticipate 300-500 shops. I would like to see 3 hours of work to start before you proceed so we know we are on the same page.
