Special needs camp prices?

I have 2 children w/special needs. Their teachers say it's very important for them to be in something, camp whatever over the summer so that there's no regression. So far, the best I can find is about $2000 per kid for 2 weeks. So I'd be paying $4000 for my kids to get 2 weeks of camp. Does that sound about average? Or does anyone else have any suggestions?
