I imagine that someone must be running something like that already. If not, someone should build it. Time to go google.
Out of interest: how many people here would pay for such a service?
Do people load test on live servers?
That said, I wasn't thinking of DOSing yourself and bringing your servers down. But I could definitely see a use for a service where it gradually increases the load till response times hit some threshold.
EDIT: I completely failed to watch the video. It is pretty specific, hopefully a joke. Perhaps the real business model here is (since it says it only accepts serious requests from businesses) to pivot to Blackmail-as-a-service (BmaaS?)
