Raising money for extracurricular

Hi all,
Last year I somehow managed to get accepted into the John Locke Institute PPE summer school and I would absolutely love to attend again this year but neither myself nor my parents are going to be able to afford it. I was wondering what the best ways are of raising money for this might be? I'm open to all kinds of ideas from bake sales to sponsored horse rides. I need to raise about £2000 within a couple of months.

Thanks!
