Please contact the ADA again and ask for Sarah Fech. I know she is licensed in PA, but she also has done cases in MA, so she just might be licensed in VA, as well. While she can't represent us (because we are in FL), she has been an immense source of help/resources when it has come to dealing with my DS' school. She's proofread documents before I've sent them, allowed me to CC her on the correspondence (because, CC'ing an attorney is the only thing that makes this school district take notice, apparently), and has walked me through some "reasonable accommodations" that I had not thought of. Also, I'm not sure if it's the same in VA, but FL has the McKay Scholarship that allows you to take federal school funds to an approved private school if your child has a medical or educational disability. I don't even know what the equivalent would be there, though.
