Help trading iPhone 5s for Moto X or Nexus 5?

**THIS IS NOT AN ADVERTISEMENT**

This is not an offer to sell or exchange. I'm simply wondering if the Apple Core has any ideas or resources that I may not be aware of for getting rid of a 5s and acquiring a Moto X (or a 32gb black Nexus 5) (other than eBay or Swappa or Craigslist). Looking to trade straight across instead of the timely process of buying and then waiting for the phone to sell or vice versa.

This is on T-Mobile.
