Home renovation for Brenden

Our son is 15 am has a terminal illness called Lesch Nyhan Sysdrome and we move out of our home we had for 10 years that was lease to own. So we bought our first home in good neighbor. But the home need a a lot of work. My brother new who head up habitat for humanity's. In Utah here. They came out and look at the home and said it would take at least 50,000 to fix the home. They only had less than 15,000. We need new windows, central air conditioner medical grade for Brenden health. A garage, with back enterance into the house for Brenden wheelchair ♿. So Brenden can access the backyard and have a way to enter the home not being expose to the weather when it cold or to hot. Brenden also had DIEBETES INSIPIDUS, he can became dehydrated within 2 hours and be life threaten for him. We have to keep our house at 72 degree and measure all fluids he gets everyday to know if he gets enough. Brenden can not regulate his own tempiture, that why the house has to be at 72 degrees. Our swap cooler will not keep the house, That cool. We need help to be able to raise this money so habitat for humanity's can do the project for Brenden home. So I hope, I can raise the money for our son Brenden. My husband is also disabled and help care for Brenden. I am the only one that works and going back school part time to get my pre-rec's for associates degree and then nursing school. If you have any other questions please contact me and ask. Thank you for your time. Thank you for anything you can give.
