We've got some bad news (Patreon)

Vimeo just hit us up yesterday talking about their business model has changed and told us that we have overgrown our basic terms of service due to Bandwidth use.  They said we had to upgrade to their enterprise plan and said we had 10 days to come up with a solution or else they would terminate the account, meaning we'd lose every video that we uploaded on there (currently @ 495 videos) We asked for a quote, and this is what they sent based off our projected bandwidth use.  We've got 9 days to come up with a solution, and we don't know what to do.
