Anyone selling pre-soldered PCB's?


I am thinking of building my own 2 player arcade controller and as i am useless at soldering was wondering if anyone knows of somebody who could sell me 2 pre-soldered xbox 360 pads (preferably madcatz so i can use on PC too!).
I need buttons for X,Y,A,B,RB,LB,LT,RT and also a Start and guide button.Not too bothered about the back button.
I live in the UK so would prefer a seller in this country if possible.
If anyone can help please message me.
Many many thanks!

Sorry i don’t mean selling as that may be deemed as trading, what i mean was does anyone offer a service like this?

Look in the trading outlet. There are some there.

Sorry i’m new to the site, where is the trading outlet? Thanks
