If Circuit City and Best buy got married and had kids

Where to start with this estate? First of all, my client is still alive just downsizing and moving with family. This house is full. I have so many things that Are beyond my brain capacity. The computers and electronic parts will take some research. But I will try my best. My client has every type of media entertainment known to man. From the high end audio components to the computers. Larry is also a stockpiler. Many unopened and barely used items. You won't need to go food shopping prior to the sale.
