My best advice to both of you if you decide to stay in advertising is to work your ass off and get a really good internship. Most universities require students to do an internship as a class, not sure if you both need to. If you don't need to, do it anyway. It will probably be unpaid, so know that going in.
Try to find the top 3 ad agencies in your area and get an internship with them. Do anything and everything you can while you are with them. Always ask what you can do next once you finish a task or project. I had an internship with a decent company, very small. I worked hard and really just did what I was supposed to. They loved me and offered me a job when I graduated. Personally I didn't see much growth in the company so I didn't take it. Seemed like a dead end and I was young and stupid.
But an internship is usually your ticket to a job. You will either get a solid recommendation from the boss of a top 3 agency, or a job at a top 3 agency. Feel free to PM me if you guys have any questions. I still really love advertising, maybe years later I'll start my own firm when I have some money.
