Hello guys,
I'm running 2 e-commerce stores and am looking for additional traffic sources as i already buy shoutouts from different instagram pages.
Im looking for Social media pages owners in the following niches :
Travel, Camping, Tripping, Fishing

We would work like the following :

First phase :

We will buy shoutouts from you in a reasonable price for testing purposes.

Seconde phase :

You will take % from the profits generated by your traffic

Looking forward for this.

Regards
