WTSPrice CHECK!!! and help

Hey Im new to this website so can anyone explain to me the steps in selling a steam account and middleman and stuff like that?
ALSO can someone do a pricecheck on my account? LINK: steamcommunity.com/id/MrProMikee

Just create a post like this and provide screen shots of the account provide a price and put a set price of how much you want to sell it for or say "I am taking offers" And always use middlemen if not trading with a trust able user
