Are you in DC or MD? If you are in DC, you might try moving to Montgomery County.
You might also try to see if there are any spots left in this summer camp. I'd also recommend asking around about any faculty members at GWU, Georgetown etc. who might be doing studies on therapies for ADHD/language delays. This is a good way to get access to top notch new therapies at no cost.
