Not possible. The reason why they are establishing the project is because they need to raise money. The tokens are their product of hardwork and research and that is what they are marketing. If you will work for them, it means that you have faith in their project and believes that their tokens will be worth something soon. They built that project out of not so much fund and your job to spread the good news. They'll rather use the money for funding the project than paying it for you. After all, you've decided to help them and they are just there for approval.
