As someone who used to make fan cards and now tests official cards, the best advice I can give you is not to spend a lot of money actually printing cards. Print on paper and slip it into the sleeves, like LibraryAdventurer suggests. Because a year or two down the road, Donald X. will make a card with either the same name or nearly the same function and you will want to change your cards. That's been my experience, anyway, and I'm glad I never sprung to have my cards printed in a print shop.
