Someone with the right hardware skillset could put one together in a weekend pretty easily, maybe 10-15 hours work or so. Skills include RaspberryPi experience, Arduino experience, integration between RasPi and Arduino, addressable LED strip driven by Arduino experience, assembly (both electronics/soldering and artistic construction/sourcing of an enclosure and the "pretty looking led strip in aquarium tube with wire stiffeners" bits).
Software is another skill required here, and for this you'll need both RasPi programming and Arduino programming, plus music specific knowledge and skills. That'll be a harder task to become or find someone with both skill sets. I'd expect top maybe be able to get the basic software for the RasPi/Arduino running in a weekend, but that iterating over configurations or "compositions" that look and sound interesting to be a long term ongoing project.
If you don't have all or some those skills, you may find people at a local hackerspace/makerspace who'll help you out with this things, but I'd expect it to take at least 5-10 times as long to build it yourself with volunteer help than it'd take someone who already has all those skills.
If you wanted to just commission someone to build/program one for you as a one off, I know a few people who do that kind of work, and I'd expect them to charge you $5k - $10k for it, if they're expected to provide some sort of warranty and ongoing support to you.
(If you wanted small run production of then, I'd guess at something like $100-250k setup for scrappy startup style hardware manufacturing design, or closer to $250-$500k for contracted industrial design from an experienced industrial design firm. Then you might be able to manufacture them in production runs of 500-1000 for somewhere around $100 each, and six months later there'd be ripoffs on AliExpress for $49 plus shipping.)
