How can I earn $50 more dollars to buy a little girl a dora kitchen?

I have $20 right now, maybe a little more, but I want to get it for her. There's this thing at my church where we take an angel from a christmas tree, and the angel has what the child wants for christmas, so I'm trying to earn money to buy a dora kitchen, but it's $70, so how can I earn more money by christmas?
