Should I hire a personal trainer?

I just joined a gym, but I don't really know what exercises to do or what machines to use because of there are so many. I'm 5'5" and 130-135 pounds. I don't really have a problem with my weight (though I wouldn't mind losing a couple pounds), but I am out of shape. I'd like to tone my entire body, but I want to focus on losing weight around my waist, and toning my butt and legs to make my hips look bigger. Basically I want to look more curvy. Should I get a personal trainer to help me create a workout plan or are my goals simple to achieve without one? If they are, can anyone give me some direction, because I feel lost?
