I'm graduating college soon and want to do something completely different from everything I've been studying... take a break to do something I really love, in a non-book learning kind of way. I'm considering doing a divemaster internship and dedicating myself to diving for awhile...
Don't expect to go do your divemasters and get away from the book learning. In DM, as well you should, you'll learn more theory than you have had to deal with in any other recreational diving course you might have done to date. If the DM course is presented properly, you should learn more about yourself and what you are actually,
really capable of as a diver in a stressfull situation despite the fact that your brain stem will try to convince differently.
You will learn more about dive theory, physics, physiology, equipment, and deco theory than ever before, and if you want the most out of it you'll have to put your mind to it and become very,
very well versed in all these subjects. You should also be able to demonstrate all open water skills practically in your sleep, with or without your mask and make it look smooth and seamless to anyone watching you. I'm saying that these are the skills you already have been taught in OW, AOW, and Rescue, but this time you should expect to demonstrate them at the drop of a dime as if you've been doing them for years and as they are second nature to you much like you probably have already mastered clearing your mask. A good DM is then not only fluent in text book skills but is someone who knows what to look for when looking at the ocean - learn to read the ocean conditions and know what to expect from them. You must aim to reach a level where you can implicitly rely on your knowledge of the sea and when to call off a dive because your gut tells you it's the best thing to do under any circumstances, no matter how much pressure people put on you. Respecting the ocean is one of the greatest lessons anyone can ever learn; indifference can be a death sentence. You will have to learn to also deal with people's insecurities, their egos, their prides and prejudices, and know where your own strength lies despite criticism from others. It can be hard work, but it can also be some of the most rewarding you can think of, if you choose for it to be.
I'm not wanting to scare you off, I personally think that it is probably one of the best ways to start taking a leadership position in your diving career which will also at the same time allow you to do something that you love, while perhaps earning a bit of money from it also. But if you think you're going to get away from learning and studying, I think you'd best consider something else. If, on the other hand you wish to expand your knowledge, skills, and experience this is a very good place to start from. But it will only be the start, whether you become a mediochre DM or a trusted and reliable one, will be up to you, and you only.

but I don't really know where to start. What to look for? What to be wary of? How much time and money to expect to spend? What to do after I finish the certifications? I'd love to go somewhere new (outside the US) for this, as the goal is really to do something new.
I'm fairly new in the U.S. so I'll rather let local experienced divers here guide you as to the hows, wheres, whens, and how much's.

If you plan on heading out to South Africa, let me know - I can reccommend an excellent instructor friend of mine that will help you develop the skills and knowledge you need.
