Kirai[1] is also huge on the spanish speaking otaku communities, could be helpful if you get him to write a blog entry about your service.

He also lives on japan, and last time i read his blog he worked on twitter.

So far in my experience, cold-contacting bloggers doesn't really work. Also, it makes me feel like a pest to try it. Perhaps if I got an introduction or met them at an event I might have better luck.
