I found this site
http://www.preschoolpalace.org/
It isn't the best I've ever seen, but at $11.99 for 10 months curriculum, it's pretty affordable. Right now, they have 2 cycles available with a 3rd to come.
Bonus, at the beginning of the month, it appears that they offer the previous month of both cycles as a free download. I have downloaded Sept and Oct for next year, because most of their stuff is too advanced for my 2 year old. I'm just picking and choosing ideas right now. It will be great next year though.
