This doesn't seem ready for a Show HN. What does it offer later in exchange for email addresses now? Convince me this isn't just another spam harvesting service, please.

I could really use a functioning service to help me find clients right now, especially if there's some mechanism to prevent a race to the bottom.

Well, this is something like "scratch my own itch" thing. I wanted to start small and build the audience. I'm afraid I'm unable to convince you other than: trust me. I'm a real person (http://jestem.tw) and I would like to solve a real problem. I hope you will sign up and I will be able to share some openings with you soon! Cheers!
