Have a look at the staff of 38 Degrees, certainly fit the demographic discussed all above, including someone who is on their second internship!
note a space- hijacker(and poster on here) is now working for them
again, don't know them personally, may be very switched on people, but disabled people had to drag them kicking and screaming to promote campaigns against ATOS/DWP benefits cuts, despite them being very prominent on members interests/nominees for campaigns.
