EVE Technology Lab

Hello all,
I had at one time paid for a spreadsheet that pulled market data and told me base don current prices what is more profitable, sell basic T3 salvage, make them into components, or sell the finished goods. Unfortunately this stopped working and the guy who made it and shared it via google docs has stopped displaying eve market data (i assume his api or some update broke it so it no longer pulls market data) I'm asking if anyone has a spreadsheet like this or can build me one they would like some isk for? Let me know, thanks

also if it needs to use an api i'd rather use my own so i'm not in reliance to someone else playing for the stupid thing to work right
