It may be possible to negotiate long-term leases of Foy or ZFX. Speaking from experience, many of our ships have "permanent" (permanent is a loose term, and for the purpose of this thread my definition is a rig installed for the length of the lease) Foy rigs installed in the theatres and ice rinks. I'm not sure how often you'd be looking to use your rig, a "permanent" install is fairly costly and most times is something you'd install only for long running shows. One potential challenge, aside from cost, with a "permanent" install is that your operators and performers will need to be properly trained and certified. Also, a rep from these companies will need to come out to do periodic inspections on the rig. All of this increases your cost and as BalletSPM mentioned below if you're doing one relatively short production then a one time use deal is probably the best.
