I certainly have no expertise in this area but I know that, here in the UK, local media (e.g. newspapers and radio stations) have often been successful in getting tradesmen to come forward, on a purely voluntary basis, to (for example) help adapt a disabled person's home to make life easier for them. These days though, appeals through Facebook for help seem to be effective in some cases too. (There might also be specific charities that can help).
[Here's an example of the type of thing that I'm thinking of:

I'm sure that there must be people in the USA who're just as willing to help. Perhaps you could find a way of reaching out to volunteer joiners, upholsterers, etc, in order to have special furniture made to meet your daughter's needs?
