So, you still have to pay some influencers for the work. In this case, you need to get everything you can for your money.
Begin by requiring that, in addition to the agreed social network, creators have to place post in all others, as well as in the blog, Skype status and send it to all contacts in WhatsApp or Telegram, print on postcards and send to friends and partners.
After that, call the influencer 10-15 times a day, starting from 6am to late evening, and spend 15-20 minutes talking about nothing. Make an infinite number of edits to already published posts, ask to change the photo, add a link or completely rewrite the text, because now it seems not right.
The creator should fully work out his fee!
