I doubt it would be very expensive to help her do this, but almost certainly there will be no profit. Your investment and periodic up-keep expenses will not be factored in as part of the cost, so to her it will seem quite profitable. For you, not so much. I would stick with quashing the idea. I've read a little about others doing similar, but the pigs got sick, which substantially increased the loss. As stated above, as long as she is not losing money, she will consider it profitable, and time well spent. Profit margins are extremely low even if you know what you are doing. If she has no experience, she (you) will lose money.
