If you do choose to do it yourself, make sure you use at least DOT 4 fluid.
You can manually bleed it or use a pressure bleeder to make the job much easier.
Make sure the reservoir is topped off with fluid, build pressure by in the system using either method and start bleeding at the wheel furthest from the driver, then work your way in. Let the old stuff flow out until the new, fresh fluid is coming out, then close the bleed screw and move to the next wheel. Make sure not to get anything on the paint, and make sure to keep the reservoir full to avoid pumping air into the system, then you will have to start over again.
