Out f your experience guys what does work the best in terms of cost efficiency and quality of clients:
1) Direct Mailing Campaign
2) Direct E-Mailing Campaign
3) Pay-Per-Click
4) Pay-Per-Call
5) Buying Leads (let's say from leadsclearance.com)
6) Advertise at local newspapers
7) Advertise on Radio Advertise on TV
9) Netowrking: BNI Meetings, Trade Shows
Direct E-Mailing so far has worked great for me. Of course, your targeted industry needs to have access to computers. Don't laugh, I have heard some people try to put together email campaigns to industries that probably do not have a computer with them most of the time.
