Laptop repair Companies?

I have a Lenovo 100-15IBD 80QQ and the charger part in it the prong had snapped off into the charger so now it won't charge I was going to try and replace it myself but I don't have a soldering iron. And I'm not sure were to take it because the inside of it does have a good amount of roach poop in it so I was wondering if there are any companies I could maybe send it to to get the charger part repaired despite the roach poop being in it?
