Getting users to items on your site

"List an item" or "Sell an item"...

[Sports Workout]

I'm trying to figure out what is the best text to put on my button that tries to encourage users to sell things on my classifieds site.

I've narrowed it down to:

List an item
List your item
Sell an item
Sell your item
Post a listing
Post your listing

Can anyone tell me if one is head and shoulders above the other? Maybe there's an accepted phrase that's better known than others...

It would obviously be "Sell your item" since that's what the person is looking to accomplish.

Sell your item.

A. Sell is good for user. List is?
B. Your is personal.
C. Good + personal = higher conversion
