Im not in the US but my experience has been that engineering faculties are reluctant to do external or remote studies but physics and such will.
In Aus each state has a central body which handles teriary admissions and this is a good place to start.
Try working your way through the phone book (or websites ) of closer institutions and fire in the question if there is a central body or part of the education dept, that might help you.
Most of our public libraries have annual guides to tertiary admissions. That may help.
I recall visiting your federal governments education dept web site once and that had a contact us link, after all they are there to promote education so they may help.
Best of luck, let us know how you get on
