Like I said, mine was for Aphrodite. There wasn't that much special stuff, just an apple. You'll probably need different stuff for yours, though. [He taps his chin, scowling in thought. Artemis, huh.]

Maybe arrows or something? Artemis likes hunting, right?

Anyway, you can probably check with some of the wisdom gods to see if they'll let you use their library and come up with something useful. That's what I did.
