Macbook Pro Early 2011 17" 2.2 GHZ Replacement HEEEEELLLLP

Hi,

I live in Belize and my Macbook Pro Early 2011 17" 2.2 GHZ video card died so I am in need of a new logic board. I was wondering if I could take it to a store near my location to fix it although it is outside the waranty. I was wondering cost (more or less) and where I can get this done. Dude to the fact I am a developer I will have to send the machine without the hard drive cause it contains sensitive information that I cannot afford to be available to the public.

any help would be appreciated
