Online Writing Jobs

I found a writing job on www.DemandStudios.com and I really want to apply. The only problem is that to be a writer for the site you have to submit a 300 word sample of your work. It has to be ehow type stuff. I could probably write something like that given the opportunity but I've never actually done it. It also asks for a resume. Something else I don't have. At least not for writing. I guess I'll be on Google tonight trying to figure this out b/c I really want to apply for this job!
