[MissMisa]

This kind of service is called a 'shopping service,' and is popular among fashion communities. It's useful for people who want things in Japan or off Japanese websites who don't have a Japanese address.

You'd be best off asking fashion communities such as EGL (Elegant Gothic Lolita) Livejournal, they often ask for shopping services, though I highly doubt anyone would trust you with any money if you haven't got a website or any feedback at all. Anime/Manga fans are often looking for Japanese goods, too.
