Latin Kit and World Kit with Session Drummer 3

I use SD3 with SP8.5.  I like all the Steven Slate and other kits that come with SD3.  However, I would like to know where I can buy or how I can create Latin and World kits (sfz files).  I do have a lot of Latin and World Midi loops that I bought but they obviously don't sound that well with any of the kits that come with SD3.
 
I would appreciate any help/suggestions I can get regarding this topic.
