Any volunteers; I am on a tight budget.

If it is for you that you need a volunteer you probably will not find one.
There is very limited information in your profile so without knowing your age and what other problems you might have it is difficult.
What type of help do you need bathing? Is it someone to physically get you into a shower or tub?
It might be worth a call to your doctors office to get a visit from an OT to assess your needs. And possibly a PT to help you learn how to manage with limitations you might have and to inform you of devices that might help make doing things a bit easier.
I see that you have posted this under Veterans Benefits. If you are a Veteran it is possible the VA can be of some help. Contact the VA or a Veterans Assistance Commission and they can help determine what resources the VA would have that can help you

Since you know how to navigate being online, I recommend you see if there's a Nextdoor.com local forum that you can join. The other members of that forum will be your actual neighbors or people who live in close proximity to you. You can post an appeal for volunteer help there. The one in my area is very active and I can usually get a response about anything very quickly.

Also, you can also start calling local churches (bigger ones) even if you are not a member or even of that faith. Ask their main office if they have a Care Ministry and explain your situation. Keep calling churches. They won't be a long-term solution but can maybe help with short-term volunteers.

We are a caregiver forum. Members are all over the US, Canada, UK and other countries. We do not supply aides.

Your County should have a Office of Aging. Call them and see what resources they have. They may have aides. Medicaid also offers in home care.
