I would consider contacting the school district to see if they could offer you maybe some names of substitute teachers.
I tend to advertise on Craigslist. Just be careful there. You will get A LOT of flakes, teenage girls and stay at home moms that are super young looking to make a buck!
I've been advertising for a staff assistant for 2 weeks or so and I've had countless college kids looking for summer work only and very young girls (16-23) with one or multiple children that are looking for work and want to bring their own children to work with them. I'll PASS!
