Can bạn guys help me?

So there's this rich prick who's always been giving me shit just because he's a bigger success than me and now he wants to humiliate me bởi making me take over this hợp đồng biểu diễn, gig, biểu diễn where I conduct a perfomance with a marching bad. Problem is I don't have one. How do I get out of this mess?
