An experienced shop can do it in 1-2 hours depending on what tools they have available. If you do it yourself and you know what you are doing, then I would say 3-4 hours. Since you will need a press to push some of the new bushings into their housings so it might take you some extra time to get the bushings to a local machine shop that can provide you access to a press. Of course, there is always other ways to install the new bushings without a press but we recommend using a press since it is fast and easy, just need to get access to one.
