The problem is that the HN front page can't be used for this sort of thing or it will be swamped with free offers of various sorts (not to mention other types of advertisements). Sadly, I don't know of a good alternative except to find some people that you like here and contact them individually. You might even have luck cold-emailing startups that are doing something in your areas of expertise.
Btw, it doesn't help that you have virtually no karma.
