When I was working for a web design company, one of the ways we acquired new leads was from the city.
Yup! it's really easy to do. Just call your local chambers of commerce and ask to speak with someone in charge of the business directory.
After that all you do is ask the nice lady on the phone if you can have the listing of new businesses emailed to you every month.
I've never had someone tell me no. It's public information.
That's it! Enjoy!
Please Note: The leads that you will get will only have phone numbers and addresses with names. No emails. So, if your scared to talk on the phone or too lazy to mail a letter or postcard... don't bother.
