I have bottle raised 6 - 7 bottle calves, 4 is the most I've ever done at the same time. All the calves I've bottle reared were given to us because other people didn't have time to mess with'em.
I think you will have better luck just giving the little guy away, around here the powdered milk is pretty $$$ so you end up spending a ton of money on them.
Good Luck, hope he finds a good home.
