A "local repairer" will probably strip the machine down and then send the motherboard off to a specialist repairer. Most won't do the soldering themselves. The specialist will have the socket in stock, cheaper than you can buy it - probably costs them around 50p / shot
if the socket is broken, its not repairable. It needs replacement
However.....there is another possibility as to whats wrong. Did you check that video I linked to? Did you notice how the socket is fitted to the board? In a cut out indent between two flanges sticking off the side of the board. Its possible that one of those has cracked or snapped, in which case repair is very difficult and involves gluing the bits back together and then trying to create new conductive traces with solder......not easy.
