Writing articles for a Technology blog in Medium.com

I am looking to hire a freelance content writer for my technology website theusefultech.com I am currently the only editor and writer posting articles on the website but I am looking to expand the website and bring in more writers. Ideally, I would like someone with a bit of writing experience and someone who has posted articles about Technology, preferably related to Apple, Windows, and Android products. My expectations are 2-3 posts a week or 10-12 posts a month.
