Hello @bradleyarrow, I don't want to spoil the fun here...
But this method of gaining votes is ultimately a very bad idea and always ends the same way. I’d highly recommend reading @anyx’s post How Vote Incentivization Degrades Delegated Proof of Stake, It’s 6+ years old, which tells you this isn’t a new topic (and no, you’re not the first, the only, or the last to offer such incentives, but again: it’s the wrong path to take).
My advice? Focus on your witness operations. That’s the real value people are voting for when they support your witness. If you’re building a business here, earning trust because you can deliver, not because you’re paying for it, should be your ultimate goal.
Hive thrives on trust, reliability, and actual contributions. Good luck.
