Try a fast dry ink like the Noodler's Polar blue ink, you'll need a good paper and maybe a F nib as it has a tendancy to bleed through the paper as it's a really fast dry ink, but it won't smear.
My daughter is left hand and has no problem writing with it with the occasional bleed with a M nib. It's like magic.
