Pirate Miniatures: Where to find Ships, Cannons, Treasures?

I'm looking for ships, cannons, treasures, mermaids, etc. that fit to
my 7th Sea pirate miniatures in size, scale, and detail. Any shops
anywhere that sell this stuff?

(Please reply also per email, since I am not a regular poster (or
lurker) in this group.)

Thanks,
