I'd need more info and will look for it after publishing this comment.
You mention the difficulty creating a marketing team because there's no CEO. There's multiple ways to deal with the issues in tandem.
1 creating or expanding the current governance feature to include certain positions, like marketing.
2 gamify the marketing needs through challenges to engage the userbase in this campaign. We have a tonne of talent here and tapping into that talent through challenges can really move the marketing along and it's a great way to 'pay' creators who's winning posts have been used in the campaign.
I'm willing to clarify if need be. Good luck
