I have a couple of foster sisters in wheelchairs on SSI. The state has always paid helpers who help them at home. (They live apart.) One is much less able to care for herself than the other, so her caregiver works more hours. They will go thru a questionnaire with you to determine what you can and cannot do, and will pay for the caregiver - 15 minutes for this, 30 minutes for that, etc, for say, laundry, bathing, housework and such.
Many times they have had a family member as their caregiver, and the family member receives a real paycheck for the allotted hours. You keep track of their time too. If there was no family member there, then there have been resources by which they could be paired up with someone. Check into soon so you can keep yourself up. Don't get frustrated if it takes a bit.
Oh, and you may wish to have a criminal background check done on the person if it is a stranger. I know I would - even if YOU pay for the bg check out of your own pocket. You must get them to sign a release first - and there are services onoine where you can get the check done. (I would check for a local agency first, though, as there could easily be fraud online i.e. take your money and do no check, and be gone later on).
