Start posting some of your ideas to your blog and if they are good enough and interesting, people will find you.

Also remember that just being an idea person may be synonym to being lazy.

The same way ideas are worth nothing without good execution, idea people are worth next to nothing for most startups. Startups run on tight schedules and insane amount of dedication and hard work. The idea of one founder sitting in the couch and sprouting out ideas may not resonate well with the technical people you are looking for.
