Would suggest to go to the computer centre in your area and ask hardware repair shops if they would do the same. At least have a pic of the broken thingy.
Try calling him. Only other choice is to search for laptop repair centered who repair mobos. Only they would have the facility to solder the pin onto the board. Is the pin bent or come off?
I have repaired several of these pins but not broken but only bent ones and even extreme bent ones.... And till date all those system are working perfect...
