HELP!

I'm new to this forum and know the equivalent of -0- about cars in general. I have a mazda protege es 01 that's making a grinding noise like a can is dragging when I drive at like 5mi/hr; sounds like it's coming from the rear. I think it may be a wheel bearing and not to do with my brakes. Even if I know how to check the wheel bearing (with ridiculous amount of effort), I simply don't have the tools. I don't think taking the car to car shop for diagnostic is the first step either for someone in my situation, so...is there anyone in Houston, TX reading this that can help me out...!!? OR Does anyone know someone in Houston,TX that I can go to for competent service and fair price who can look at my wheel bearing or brake AND fix if needed? Help!
