Ideas on how to raise money for my best friend?

Hi guys! I need some help/ideas. My best friend suffers from a muscular/ nerve disease that is similar to ALS, this means his muscles are slowly atrophying and has confined him to a power chair almost all of the time. Due to recent changes in his condition however he now has to use his power chair 24/7, which also means inside his house as well. Unfortunately, his wheelchair will not fit through his bedroom door and he does not have a handicap bathroom. His condition will keep progressing, and his family needs major donations to remodel his bedroom and bathroom so it gives him freedom to be independent. I need ideas for fundraising for his remodel, any ideas are welcome and will be considered. Thanks!
