but i am in need of help and dont know where to try and get it from

I am deaf person, living on monthly income from SSI, with my wife and 2 children which are all disabled. My wife lost a child almost 8 years ago and the two children that followed each have disabilities so I am trying to find a grant to help us buy a home and a maybe a grant for me to start my own painting business.  I have 9 years experience in painting, but as long as I find a program that will help me find somekind of income aside from my fixed SSI or the grant to help us in anyways purchase something of our own would be a great gift from above...
