Just search for "reconditioned steel drums" or "drum recycler" in the Fresno area. If they are certified, then supposedly all the drums are run through a blast furnace to burn up an residue left on/in the drum and then media blasted to remove all the charred remains.
I was able to get my drum for my R2-BQ UDS project in the LA area from a drum certified recycler (Apex Drum) and got a bare drum off of their processing line before it went through paint. $40 is about the going price for them.
I know a place in Hayward, CA that has them, but there must be a place closer to Fresno. Keep the faith, the drums are out there.
