Needed cheap or FREE (Rustburg)

Wanted 55 gallon barrels metal ok.
I could also use huge used flower containers.
My dear friend is 92 years young and wants a garden if I can get the barrels which we can cut in half.
I will personally buy her soil and plants and make sure she has a little garden.
Thanking you in advance for any containers you can provide.
I have a cousin that will pick them up.
