Customer Service for Gym Equipment + Assistant

I'm looking for someone who is self motivated and can take initiative on task at hand. I need someone who can help post listings on craigslist, ebay, offerup, facebook, and other platforms. The main inventory we deal with is commercial gym equipment, so a background in fitness is a plus, but not necessary. Need to be able to help set appointments and repost along with other basic assisting with other projects.
