To the OP - while it's great that you're making this proposal, there's no guarantee that these animals will even breed, it's unlikely that breedable weight females will breed in the same year that they are moved from one location to another, even within your facility.
Most breeders who have to make a move, usually just write off that season, because they understand just how sensitive the females are to changes, and know that it can take up to a year for them to become receptive.
And then there's the bit about marketing your animals. You'll be a relative un-known in the market. You may end up having a bunch of animals that don't sell. And a higher food bill to feed those extra mouths.
It may seem like a good investment for you and your step-mom, but you're not going to make it back in 12 months, not even close.
