Do you by chance write any fic for this play? *hopeful*

Um . . . sort of. There is one Caroverse story that crosses over with The Merchant of Venice. It's called Not In One Bottom Trusted. The POV is Antonio, it's set about five or six years before Merchant of Venice takes place, and some of it is set in Venice.

Or know where I may find some?

Definitely check out the good folks at bard_slash. They've got some good stuff over there.
