Try to get your hands on some cheese, carrying 50 could feed a two man caravan for a month or more. Goat cheese is the most efficient weight to calories ratio, sheep is the best tasting, and cows are a nice balance. Industries are good if you plan on making tons of money, but it requires a heavy investment. The clothing industry is probably the most efficient route, clothing is very light and weighs around 0.25 a piece, enabling you to carry much more. If you have enough cash you can start clothing+breeding+cheese. Then you can make your own trade route. All you'll pay for is forage, water, and your employees. You can get leather from breeding, turn your milk into cheese, turn your leather into clothing, then get ready to sell them. Make sure you check where your good sell best. Don't be afraid to try the other industries that I didn't list, almost all of them are profitable, just some more so than others. PM me if you have any specific questions.
