WTB: Steel cylinders, 117cu.ft. & larger, SoCal ONLY

I am looking to purchase used steel cylinders, 117cu.ft. & larger. I prefer to meet and pickup in San Diego County, Riverside County, or Orange County, but I will consider good deals in other Southern California counties. I have PayPal, Zelle, Venmo, CashApp, NFCU. Thanks in advance.
