Where can i sell renting?

Hello, first of all, I dont know if I'm placing this in the right thread, if I'm wrong, I'm sorry.
I have a YouTube channel with more than 230k and more than 90M total visits. I want to rent advertising, for example: rent the first line of the description, upload a video to my channel, direct link from the video. The problem is that I do not know where I can look for those types of people who look for these services. Please, if someone knows of any method, share it with me.

I want to make money with my channel because I cant monetize my videos, I listen to some ideas.What would you do?

SoundCloud rappers will be your bread and butter.

I remember you mentioning it’s a Latin music fan base. What kind of artists do they connect with?

You could go a step further and sell branding and promo services if you partner with someone familiar with other platforms.

Many artists are poor, but there is always those that if you can prove your potential usefulness that can break out the credit card.

So, you advice me yo go to soundcloud and talk with some latin artists?
