I started a bricklink store a while ago.
It was marginally successful, and could have been much more so if I had devoted the time.  The approximate inventory of that story is now being put up for sale.  The pictures illustrate more or less what the inventory is.  An Excel file contains the entire inventory and can be viewed by downloading it off this site.  I parted out new sets, so I also have lots of pristine instruction booklets.  The parts are sorted by color and then somewhat sorted by shape, so much of the sorting work is done.  The pieces came mostly from Star Wars, Harry Potter and Train sets.  I have a number of difficult to find pieces, sets and characters.  Have a look around, and if you are particularly interested in anything, let me know and I will send a picture, verify the quantity, or whatever else you may request.  Thanks for the interest.
