Utah is blessed with an active and broad Martial Arts community. These guys in particular are exactly what your looking for. They teach practical self defense covering all modern scenarios and how to do it with power. If your not local to them, try to find something similar.

They have pricing geared toward how many classes you attend per week, open Friday practice for students, regular Saturday seminars, and ask for payment on a monthly basis.
Years ago (mid 90's) my friends and I were looking for the same thing, having read the Tao of Jeet Kune Do we were looking for something that was actually not restrictive in style, and not a sport, and more all inclusive of many styles or anything effective, it seemed logical that someone would teach the best that can be learned from any style? and above all just plain practical, ie street fighting is no rules, how do you actually defend yourself? We found it in all locally in a man named Tom Garriga. While he is out of state now, he comes to Utah regularly for seminars and these guys at Tang Wei are his advance students still progressing the system and passing that knowledge on.

It's a lifestyle change and the biggest sticking point is practice, you get a couple months in and kind of fall behind and though you can keep going it won't start sticking without some regular practice. One thing I like that they do now is 1.5 hour classes so you get some practice in class. But it's something you'll want to prepare a place to practice what you learn in your home, if you don't have a lot of space, prepare a little open area...
