Here you go guys. The PC is actually in the ceiling, I run it with wireless keyboard/mouse, I used an USB extension to plug in a receiver and kind threw it over the ceiling closer to the counter to ensure stable transmission so basically transmitter is over my head. It cost me 2x $219 for 2 39/40 inch TV at best buy, 2x $25 for wall mount brackets @ Amazon, a BS dual core dell Dell Optiplex 755 slim case PC, $85 @ ebay, $100 for a video card that has 2 HDMI outputs from Amazon, $ 20 for 2 HDMI cables, $30 for wireless keyboard/mouse from Staples. A little effort.
Once we created a main account at trello, I had every employee create one of their own and invited them all in to this board, not only this exists on 2 bigsceens, everyone can add/change/update status from their workstation, also I can do this from Samsung Galaxy S4, so where ever I am, I can take an order, punch it in with all the details from what I have just discussed with the customer, add a note and take a picture of, lets say a customer's BC and attach it to the order! Everything being added/updated instantly, it keeps a track who did that so if Julia added a note after talking to the client, it will say "Note posted by Julia"
