That's up to you and depends on whether you have or could get the necessary tools and whether you want to learn something new. The links I posted tell you all steps necessary to complete the job, and any other questions could be answered by posting them here on the forum.
If you decide to have the work done by a mechanic, choose one with experience with Hondas. In addition, when the work is done, seriously consider also replacing the timing belt, belt tensioner, and drive belts, if this work has not been done recently.
