I only found these two from Reaper:
Female mageMale mageUnfortunately, they're both holding staffs around which the snakes are wrapped, rather than holding the snakes directly, but it's the closest I could find.
Then again, you could trim the staff off, add a piece of wire with the snake head on it (taken from the staff) to the hand and sculpt the snake's body on with a little putty. Pretty simple to do.
