Kin is not a crowdfunder or a way for an individual to raise money for a private need but you can set up a group because you need something right now.
It is expected that you will contribute to the group by the amount you requested or in the manner you agree with the group. In this way, the group should all benefit in the end, not just you. So, if you set up a group for a specific purpose, make sure it is clear how this will help your community and don't let them down!
