You are looking for pump and dump group in simple words? If so, I doubt anyone knowing that would be interested to invest in your project. It's really an unethical behavior. If your project is good one and have something of utility, volume will increase automatically. You would rather spend your time on developing the project.
They are looking for potential buyers , as if they can easily find one here.
I will suggest you something .if you really want to have liquidity in your project you should work with your roadmap and build your project alone it will attract more investors if they see that developers is really qorking for his own project. Volume and liquidity will follow after they see the potential of your project.
Instead of finding a people to help ypu make your own proMotion instead.
