How should I get my iPod Mini's battery replaced? - mini battery blender

I thought about replacing the battery of my iPod Mini. Should I try to replace me, or I should do a technician? Also, I live in San Francisco. Does anyone know a place where you can replace the battery of the iPod Mini to pay is for you? I asked people at the Apple Store and they said they did so not because they are not compatible with the iPod mini more.
