good job on the work that you're doing. Running a charity is not easy.
Here are the contacts, I hope this will help you.
Paccom (in Hanoi)
Robin (in Hoi An) She also has a charity for disabled children. She's registered with PACCOM, so if you need to contact her, get some info from PACCOM. Her charity is called Children's Hope in Action.
Sr Van Nga Le (Thich Ngat Hanh School for the Blind) in HCMC
There's a cafe that employs deaf people in Da Nang. I can't remember the name though. If you go to Da Nang, I'm sure you can ask a local to direct you to it.
There is also an NGO in Hue called Hue Help. I believe they are based in the UK.
Kirk Horton is based in Thailand. You can contact the Bangkok School for the Blind.
Sabriye Tenberken (Braille Without Borders) She's in Tibet and India. She had a rough time too for the same reason, no one believed her and she had to deal with a lot of red tape. She's famous now, you're going to be famous too one day. Don't let people stop you from what you want to accomplish. I think what you have done is very brave.
It's ok to make mistakes as long as you learn from them. The real idiots are the ones who can't admit to their mistakes or keep making them.
BE PROUD OF YOURSELF! I love the name of your charity, btw.
