Here's a tactic that has worked for me so far
1. Set up a blog on your domain
2. write 20+ articles on industry-related topics (this alone will bring in some traffic)
3. get a number of emails from prospective customers
4. write a PERSONALIZED email to everyone on the list and ask if they are interested in an interview to be published on your blog. Offer a link from your blog as additional incentive
My response rate so far was >80%
