Fundraising help-something quick!?

Ok I'm doing a fundraiser for my youth group and I need $500 in like 2 weeks. I'm going to california to be on 3abn (my church's tv channel) and im telling them about our mission project and our outreach we've been doing. We've been making blankets for unwed mothers at the university hospital and now we've been invited for a youth conference to tell about it. But no one has any money in our group but our tickets have been bought by a loan from the church. And we need to pay the money back in a few weeks. I dont know where to get it from. any suggestions would be helpful.
