Via CP Development, here's a list of five ways to make money using data extracted from the web.

I'm not entirely convinced by #1:

1. Extract a list of your prospective customers (from a business directory, professional association website, competitor's reference list ...) and employ sales force to offer your products&services via email, telephone or postal mail. Sweep the entire prospective market for as low as $1,000!

I've been in marketing for a long while. I'm not sure you can do a *great* job of sweeping the entire market for $1,000. It takes time to find, filter and clean data and more time to contact that market. Most people won't convert on a single "touch". But it may depend on your market and how you go about contacting people.
