I was talking about actual services, you like marking designs for someone or even buying goods. There's the #hivelist community but not many people use it.
But as for what you talked about...
The vote bots are frowned upon on Hive, but there are services that allow you to pay to get votes like @dustsweeper which doesn't give you any profit but prevents your loss from low-payout posts, and ecency.com in which you special points to pay, (not Hive) and @ecency's curator has the right to curate your post or not depending on their own criteria.
