(This can be done on approximately a $100 budget in Ogaki, so that's probably the upper bound for you. If you can't afford that, write up how this advice actually worked out for you in a blog post and I'll reimburse you.)
Invite people via pre-existing networks like e.g. the Chamber of Commerce, which is generally happy to tell their members about free events which aren't (explicit) sales pitches.
When meeting people, ask about their business problems. Listen. Tell them that you understand those problems. If appropriate, say that you think you can produce a solution to those problems, since you are in the business of doing that as a technology consultant, and offer to discuss that problem in more detail after the event.
One thing that programmers forget is that, at some point, you weren't good at programming, but over time, you learned and now you are pretty good.
Your business/social skills may be at that same starting level, and this isn't something you read about on the internets and are immediately good at.
Start now, plan on doing this over time, and learn to get better at it. It takes effort, but it will be worth it.
That right there: "One thing that programmers forget is that, at some point, you weren't good at programming, but over time, you learned and now you are pretty good."
That's just an enormous revelation. I can't even tell you how good it was to talk to Dave Rodenbaugh and he basically said: "See, you are now good in giving talks. Do you remember the first time?" and I was like: "Yeah, I remember: I nearly cried afterwards"
And I needed someone to tell me this!
Look for someone that impresses you - both technically and professionally. Someone that, if you could succeed in patterning yourself after, you'd consider yourself fulfilled and successful. Grab their ear, pick their brains, ask them for advice. Show them your interest, enthusiasm, and aptitude - and earn their respect. Hopefully, they'll help you get to where you want to be.
If you don't do _anything_ else, fill out your HN profile with some contact information. Right now, you're making it difficult/impossible for potential clients/employers to contact (the Hacker News) you. Why?
