Making an Email List for business directory

hi I need a list of email addresses from all parts of USA of the following individuals, companies, freelancers or people working in the field. 1. Wedding Videographers. 2. Wedding Photographers. 3. Album Printing services. 4. Wedding event planners. I will give hints of some sites from where such emails can be collected. Only genuine people please and I am not interested in person who bid for all projects blindly. Put "my name is bond" as a first line of your bid else your offer will be neglected. I want a clean email list, checked for invalid emails. Once USA is done, we will go for other countries. bye Raj
