Online camera repair shops

I found an online shop that does camera repairs & offers the repair of my camera model; http://www.darntoothysam.com/products/Sony-Cyber%2dshot-DSC%2dH5-Camera-Shutter-Button-Repair-Service.html

what does anyone here think to this? it is a lot less expensive compared to Sony, I read online Sony quoted people for shutter button repair at 180.00 dollars.

I am located in Ca, USA, & this camera repair place is in Minnesota, USA, so my camera would be traveling quite a distance, is this a legitimate place to have my camera repaired? if not what else should I do? another option is to buy the button directly from Sony, they sent me a part number for it, & try to replace it myself, or take it to a local camera repair shop in my area.
