Outside sales?

About to start my first job in outside sales. Any tips? Assuming it's going to be hard getting businesses to sign contracts and cold calling.

Just selling shoes for a few years. Very laid back full service shoe store. Worked on several political campaigns. Even at one point was running for local city commission. So I have much experience with people, especially the wealthy.

Contracts. For businesses to buy from us. Thinking of the rep's that came to the store I worked at for a few years and how they went about things. I sat in on several meetings where they would try to get my boss to carry their products. Often they brought coffee and food, might try that?
Need to get some more dress clothes, down to 4 shirts and 2 pairs of dress pants. Too hot here for a suit, but a vest will work. If I make the cut and last til it's cooler, i'll get a suit.
