Eventing Summer Camp help

Hi i'm looking for an eventing horse camp for this summer.
I'd like it to be...

1-2 weeks
Have school horses to use(i don't own my own)
If it is more 3 hours from washington DC than the camp needs to be able to pick me up from the airport
It can be international
Less than $2000
Have an eventing program or at least a good cross country course

Thanks
