Most indoor ranges won't help much
Indoor ranges can be difficult training areas for IDPA and IPSC. Depends on what the range allows. So many ranges won't allow rapid fire or drawing from a holster. I know one indoor range that won't even allow double taps! Some won't allow lead bullets...and I'm not going to work up a FMJ load just for these places.
If you can get to an outdoor range with bays to rent, then all you'll need is a timer with a delay function, three stands, 1" x 2" wooden stakes, and some cardboard targets. There you can do El Presidente and Bill Drills (search for specifics) or simple "draw and fire six shots" practice. Indoor ranges are for Bullseye practice...assuming they allow lead.
