If you are willing to take the school kids there is also the option to advertise for part time care such as a mom on mat leave that wants the older child in care a couple days a week or someone who works from home. They would be able to work within a 9 am drop off and 3pm pick up or whatever you need and also work around PD days. The end result is it would be like getting paid double for the space. Priority for space of course goes to the school kids but again the mom at home is flexible. And come next year you have a better chance of getting both of those kids into care when mat leave is over.
