1. Create a white paper about how the value that a company in your target market gets if they use your service. What's in it for them to hire you? Why is it better to hire you than do it yourself?, etc.

2. Find email addresses for the right person at companies in your target market. Send them a short email that introduces you and your company, and offers the white paper. Don't try to do any selling. If they email your back, then send them the white paper. Tell them that you will follow up with them in X days (actually give the date). Also tell them that you will add them to your newsletter list, which you do not share with anyone, and they can unsubscribe at any time.

3. In X days, send them a follow up email, asking if they received the white paper, and if they had any questions or comments. Also re-send the white paper (or link) and say you are resending it, in case they didn't receive the first email.

4. in a week, follow up again.
