Do anything. If both sides have no interests, they can't achieve it, so you must make it clear what benefits the other side can get from your sponsorship, and you'd better write down the benefits of the other side by yourself, and then say it again, and you must have a particularly good attitude. Let people think that you are a man who can handle affairs. Of course, don't forget our own interests. Everything is based on interests!
I hope my answer is helpful to you.
