Motherboard stuffed request for help

Hi,

My Dell Studio 1558 motherboard is broke. I am having trouble getting a reputable Dell repairer on the NSW south coast. I sent it to Laptop rescue who confirmed what I already knew, that it needed a new motherboard. It was like pulling teeth to get an approximate price for relacement but when I did it doubled in price on arrival to them.

So what I need to know is there anyone on south coast I could send it too?

and

what should I expect to pay for parts and labour as a guide?

Thanks for reading my request for help,

Daniel
