What a budget gets you
You don't need to arrive knowing which channels you want. Give me a number and a goal and I'll put together a plan. A few examples of how that usually looks:
A single integration on Cherry or Lonox is a low cost test. You'll find out within a week whether the audience clicks on your link.
One sponsored video on Lynix or GrammaCrackers puts you in front of a few hundred thousand people, sometimes a lot more if the video takes off. Food and drink brands usually start with The Good Boys, since taste tests are a big part of what they film.
If all five channels run your read in the same week, you're looking at roughly 850,000 views from one round of uploads. Repeat that over a month, add a few more creators, and the numbers keep going up from there.
Pricing depends on the channel, the format and how long the read is. I'll give you real numbers once I know what you need.
