Nice work. Have you considered creating a page/blog post the explains how you've used your own tool to find paying customers? Doing that would provide a ton of value I think:

1. You'll (hopefully) find new customers

2. By using your own tool regularly, you'll gain invaluable insight into UX issues and new feature ideas.

3. Potential customers on your site would get to read through a play by play story about somebody successfully using your tool to drive business results. Basically a meta case study.
