Fortunately for me (and for the other kids) that is usually about 1-2 hours each morning (both of them) and then are both awake over lunch time and will go back to sleep around 2:00 and then both are picked up...one at 3:00 and the other at 3:45.
They both come fed (one at 7:45 and the other at 8:30) and don't need to eat again until right before their morning naps which usually falls anywhere from 9:30-10:00 until 12 noon.
I didn't put them on any type of schedule, just requested that they be fed right before or as close to drop off time as possible. Nothing worse than having to take a child in and IMMEDIATLEY have to feed them.
My babes are 2.5 months and 7 months old.
I think you won't necessarily have too much trouble with having 2 infants there IF they are good sleepers and eaters....which it sounds as if one of them might not be if she requires rocking to sleep and resists the bottle. THAT one might prove to be tough.
Neither of my babies need to be rocked or encouraged to take the bottle (both are BF) but both get laid down fully awake, changed and with full bellies and go right off to sleep. Both sleep right in the kitchen/dining room area right smack dab in the middle of all our acitivities so no quiet room, darkened environment or white noise machines. They just go to sleep.
I think you aren't really going to know the answers to your questions until you actually do a few days with these kids because you can't force a schedule and what the parents say they do and what they actually do has to match as well as the temperament of the infants being a big part of what your day will be like so until then, I think you would be just guessing. 
My 4 mo that arrives at 7:15-7:30 each morning ALWAYS arrives hungry. It's a bit annoying, but I wasn't sure if I should say anything. She is part time now, 2-3 days a week, but will eventually be 4 or 5.
Thankfully, she DOES sleep on her own quite nicely. Otherwise PT baby would not be possible because I am NOT trying sleep train a part timer...
oh, wait...yes I am! 11mo gets rocked/held at home, and she's only about 2 days a week. Here, its CIO, sadly, but she's been doing ok with it. Luckily, I have a room waaay far away from me, because it breaks my heart. It started out 15-20 minutes of crying the first week, now she only fusses for a few minutes.
Back to OP...it's pretty tough to get a baby on a "schedule" before 6 months or so, and if they're br. fed, even tougher...my br. fed munckin last 2 hours at most between feedings.
