Open Question: how can i earn $500 dollars in two months?

My relatives birthday is on July 5th and i want to fly out there and surprise her since she hasn't seen me since i was a baby. I've found the cheapest tickets on a reliable airline and i've calculated all costs, which come out to around $500. I want to purchase the tickets to fly out there by about June 15th, but i'm only 14 so i'm not sure how to get the money. I asked parents for extra chores, but what else can help? I really really want to do this for her and i really really need help! thank you!!!!!!
