Off the top of my head, I can offer just a little.
Rabbit does will breed very quickly after having babies, so technically you could have a litter per mom per month almost. That would be awful hard on them though, trying to nurse one litter and being pregnant with another. So I would definately keep the male separate from any female that you aren't wanting bred--it only takes about 20 seconds and DAY-amn are they fertile! I also had a doe once who accidentally got in with my buck at 4 months old and had a litter. She wasn't able to care for them properly and we lost several before it was over.
Keep in mind as well that rabbits are very sensitive to heat and will die of heat stroke. Their teeth also never stop growing so they need sticks etc to chew on to keep them worn down to the proper length.
