What is the fastest way to make money in 2 days?

baically, I want to get Call Of Duty black ops. I have no money. It's 70$ including tax and im getting an xbox 360 headset to totally to about 100$. I want have a list of things that i want to sell / get rid of. I am only 14 and i dont think the pawn shop will let me sell things there, so gamestop is an optional seller/buyer. I have a wii (white), call of duty modern warfare reflex, redsteel, resident evil 4 (wii),the simpsons game (wii), guitar hero3 - 5, resident evil 5 (pc), a c2 palm ibm PDA, A bunch of ps2 games ( at least 20 of them) , old cell phones ( motorola, at&t LG ( dont know the models)). an ipod 2g , presario compaq 2003 computer desktop, 3 wii guitar hero guitars, 1 mic, splinter cell conviction,a ps2 , an xbox (original), and a bunch of other crap. I dont really want to sell the wii but is there another way of reaching this goal witout sell stuff?
