Your question is confusing - you say 'even if I did get a new battery, I can roll it back by myself'.
If you can roll it back by yourself, then do so. If you need assistance, get someone to help you.
If you *can't* roll it back yourself - and can't find anyone else to help, you might be able to use another vehicle and a tow strap to move it. I recently moved my '65 Mustang that has a totally dead battery into my garage by myself (down a fairly steep hill) with a Nissan Versa Hatchback. I took it slow, stopped and adjusted things as necessary, and it went right in.
