Being someone who is also actively looking for a tech person, from my experience you need to do a lot more than throw a post up on Hacker News, including being more transparent about yourself.

It wasn't until I launched a product (which i had developed by outsourcing it), marketed it up to 5,000 users, got paying customers till tech people payed any attention to me. I have also have deep industry knowledge and connections that help.

You don't need a tech person to get things moving. Outsource an MVP or prototype. Spend a little to get someone interested and excited.

Just my 2 cents.
