Selling account. many games!

I'm brand new here and have no Idea how this will work. I'm willing to do whatever. I'm selling my gaming rig and no longer need the account so its gonna sell. I'll list the games and then interested people can chime in and hold my hand through the process. I dont know what "I'll go first" exactly means. but it seems to be important. I'm assuming. I give you a game or something, then you pay, and so on?
Here are the games

ARMA2
Braid
Company of Heroes and Opposing Fronts
Crysis wars and warhead
GTA IV
Race 07, GTR Evolution,STCC
Rainbow six Vegas 2
Red Orchestra
