Have you tried Kijiji? This is where I usually get my assistants from, but I don't ask for ECE, ECA, etc. since they are most of the time under my close supervision, and they are much more expensive if you want them to last

I'm also closing for 2 weeks, all parents have made alternate arrangements during that time. After that my assistant will take over under my supervision for a few months. I also have educational program included some part of the day, but I have made it easy for anybody to run it without needing a higher degree or too much work.
