You should tell us more about the games you want
But if you say that people charge to much, probably you won't find anyone for your request ...
Obviously if you want a platinum for 1 or 2€ ... it's hard to make business with you =/
We have to buy the games, and it takes time to do the platinums ... so it's not for free X_x
Don't hesitate to give us more info about what you want (what games), and your budget for it ^^
