I would suggest to contact Nepalese Association of Houston (NAH). They use to collect money for several victims, like Katrina victims, Burma Cyclone, Earthquake in china, koshi Victims and recently they helped Bhutanese refugees also. I hope they will definitely help you however they were very silent and they did not seem to be very helpful before IKE attack in  houston.  Try your luck....... after all they are nepalese.
