I've already built a currency converter calculator in C, and it was be easy to adapt it to this, so long as base data is available to sum up for the trip. In other words, I don't want to have to invent a Traveling Salesman Problem. I have 7 yrs. experience in C, 7 yrs. in Java, and a BS in Computer Engineering from Carnegie Mellon U.
Also, I'll do it for $85, but I wasn't allowed to enter that figure.
