Thanks Chris,
I've actually already contacted Cal-Earth and have also tried locating the graduates who helped with those projects in Pakistan way back - unfortunately, have not heard back yet from Cal-Earth and the project site for the re-building in Pakistan is down last I checked and can't seem to find the alumni who worked on it (though I spent an hour or so trying).
I will be doing some more research this next week to find other alumni who may be interested in coming here to teach a workshop - and also possibly posting in other forums to locate some instructors. I actually just had another opportunity come our way today of an offer of some land on which to build a model village and/or other structures and working models closer to us here in Karachi at the moment and won't even have to source the funds myself (BONUS!) - which is logistically easier for us at the moment as well - since we don't have our house built in Chitral yet.
Thanks for the suggestion we're totally on it!
