Maybe you've heard of something called time. That is a problem. If you think you can get it down to some kind of automated algorithm, good luck. Like I said, the input will be crap. Have fun proving Mr. Martinez is Mr. Martinez. People like us, who are waiting in line, have already provided the nec input. And paid up too. That's where you solve problems. Not by catering to the dudes at Home Depot who dont trust you, can't afford the fees, and have documentation you can understand if you're lukcy.
