How do I sell uniques that I don't need

I'm a casual gamer mostly playing self-found in Standard. From time to time, I find some uniques that I don't need (some latest catch were Thousand Ribbons or Perandus Blazon). I don't want to vendor them, as they only yield me a couple of shards. Linking them to /trade 1 doesn't help, as /trade 1 is generally overwhelmed with massive and better offers.

How could I sell those uniques to other players? Or, better, how do I find players in need of those uniques?

I'm only playing 1-2 hours a day, irregularly.

EDIT: For anyone reading this question later than March 2016, Premium stash tabs are more convenient than Procurement. Premium stash tabs are paid, using Procurement is still free.

Use Procurement and set up a shop. It's never too early to do that.

People buy this sort of uniques by looking for the cheapest online seller on poe.trade. If you appear online on poe.trade (Procurement has a feature to do that automatically for you as long as the program is open), and have one of the lowest prices listed there, they will contact you. Bingo.

You will occasionally sell items for less than their value. It's perfectly normal; forget it, go on, and learn.
