Help me surprise my sister with a trip

I'm 17 and would like to surprise my sister with a trip to America to visit North Point Church and friends at Browns Bridge church that we met on a mission trip in South Africa, but can't afford the tickets.

I'm trying to save money but I can't make any because nobody will hire me. As I'm short and look younger than I am. I have tried the only job I ever got was rewiring reports for a lawer but I had to do it from home.

The reason I want to take my sister is because she has helped me a lot through the period of time that I was depressed and keeps helping me to not go there again. She was basically my counselor that just listened and cared.

So I need help, please. I have limited my campaign that if I don't raise the funds by May 2019 the trip is off.
