I am selling for my friend, what is the preferred escrow? Not that i have experienced in selling

Hi, i would like to sell my bitcoins at low rate. 1 btc @ $230USD : 2 btc @ $459USD

This looks nice.
1) Always be active and find hobbies, eventually i met my old schoolmates and they turn out to be successful compared to myself.
2) 25 years old
3) Do not be afraid to make mistakes
4) Have my own armored tank
5) Karma will bite you back, do not mind what others say, just do it
