I've been a DIY'er for a while and wanted a gas stove in the kitchen I'm DIY'ing but didn't want to have a 3rd party propane company involved as the tank is massive and they tend to fill it up whenever the Propane is most expensive. I figured the job would have cost around $2K for the tank and the black pipe plumbing. So I poured my own little concrete pad, got a two 30lb tank setup for an RV and bolted the tanks to the pad using all thread and epoxy and plumbed all the black pipe myself put in a two stage regulator. Pressure tested and checked for leaks. Works great. Total cost around $200. It's only feeding small gas range so expect the tanks will last for months and as I put in extra valves I can pull one out at a time and just refill myself. I use solar for everything else.
