Samples. You’ll need some samples before you can really begin marketing yourself. Figure out which market you want to approach first, and then find or create some related samples. For instance, if you want to try your hand at blogging, study some successful blogs, and then write a few posts of your own to use as samples. Do this for any and every market you’d want to write for.
Hunt for under-priced used books that you can sell online. Download an app that reads ISBN numbers so you can scan the barcodes on books. This will pull up the book’s current price on Amazon so you can see if it’s worth trying to resell it. Then, visit used book stores, thrift stores, and garage sales to look for high value books. Post the books for sale online using sites like Amazon or Ebay.
