Is there a resource that can help me get a mobility hauler to carry my power chair?

I am 53 years old and I am disabled, I have a power chair but no way to get it around to where I need to go, grocery shopping, Dr's visits, and church. I don't make much on my disability check so I was wondering if there is a resource to get a mobility hauler and hitch for my car to be able to go places I need to go. Thank you for your assistance.
