Anyone looking to hire Everdream (or any other advertising agency) shouldn't expect such a tiny rate for such awesome work. You see, that price tag doesn't figure in any kind of post-production work like visual effects or pre-production development, both of which could have been handled by Khabushani and Collins. Likewise, equipment and software costs (even if already owned) would need to be part of the costs, but there's no mention of cameras, lighting, microphones, computer graphics software or music production in that $1,500 price tag.
Though it might sound romantic to say that the killer commercial barely cost anything, that's all it cost Everdream itself to make the piece. No reasonable business owner should expect to pay a similar amount for anything remotely close in quality. That being the case, Evergreen's Tesla advertisement is far less for the car company than it is for spreading their own name. And, unless Khabushani and Collins are willing to work completely free, that'll be the last $1,500 commercial they ever make. Especially since Tesla CEO Elon Musk hinted at a future collaboration with Everdream on his Twitter account, writing, "I'm confident that Tesla will do something with them."
