Making Money Stuff.

I have been trying to find freelance jobs on upwork.com. Basically all of the jobs require writing samples or a writing portfolio. I think I can't really submit this site as a portfolio. So I need to start making one. I might start a different account on another site to start making this portfolio. I need to make a long portfolio so it would look like I was spending a lot of time writing it instead of spending the past eight months on this site as well as my Youtube channel. I don't think either site of mine would be good to present as samples and portfolios.
