I recently saw a video, by a CNC guy with a good sized commercial shop, recommending that you limit your selection to those items that routinely sell, otherwise, as noted above, you tie up stock, space and money and you have spent all three on product that may not sell. Obviously, it takes a while to figure out what sells, but unless you are truly customizing every board, IMHO his approach makes sense. I will see if I can find the video.
