Where I live there is an organization called The Center for Independent Living, an organization that helps disabled people. You may want to call the Salvation Army or Red Cross they would also be able to point you in the right direction.

Local Social Services Dept.
Health Dept..
They may not give you personal info though, as there are Privacy Laws..
They could point you in the direction you want.
What if you posted in the paper,that you will sit/or be company for those that
need someone….
Consider your local church, the preacher/priest may help.

You could see if there’s a list at you local hospital. Senior citizens center. Places like that.
