Do you know the project owner? How many project teams do you currently know? Do they believe in you?
Even if you know the team personally from the project, there can be no guarantee that they will offer you for a bounty manager job, they need a bounty manager with the potential to raise the project's rank above other project competitors.
How many followers do you have so that the success rate of the project you are promoting will reach the target?
Being a bounty manager is very easy, but what is difficult is getting the trust to campaign for projects from the team.
As much as possible not limited to the number of followers to support the successful development of the project being promoted, we must make a service for good management before promoting any project.
