Well I would go to most active. Usually the way to appear there is the ones with most comments. You'll miss some but I bet people will start commenting links to other posts or will direct message you(after they voted of course). Then you can provide links so people can vote (and comment) on those post and lastly when you are paid you can send them the sbd. (I thought @furion steem.li used to have a sort that would help like that but it's not working. )
It's a lot of work but if it gets attention some whales will latch on.
