We have used the promotion service by @steemium thrice and had a great experience with the application and the support staff.
It is a great way to get maximum exposure to steem post to attract potential voters and thus bringing maximum profits to the users.
We will strongly recommend @steemium if anyone has a need to promote quality content on steem easily and profitably!
