Do charities help the disabled with yard work?

[Aurora]

I have an interesting question my wife is disabled and the house we live in has little to no shade. We are in desperate need of trees to be planted that can provide shade so that comes the summer she will be able to go outside. Ideally we would like a church or charity to do this. We also want other yard work done like cut some bushes and mow the lawn. If we do not get the tries, the sun make her symptoms worse. Are they any charities or even government programs that can help subsidize this?
