I need to raise money

I need to raise about $300 from now to Aug. for a women's retreat in PA. I need some ideas of how to do that. Last night I looked at writing articles for the internet but wasn't real successful at finding the right webpage that wasn't a blog page. I am trying to take $10 a week out of my Ebay selling to put toward it. But would like other ideas. I know, I am usually the person that has the ideas. So suggest away!!!
