The benefit of DIY is you can learn so much along the way.
If you want to let the shop do it for you. Make sure they have experience on Euro or similar, Coz I heard too many case of snapping plastic clips or plastic bolts here and there while they remove parts out (sometimes they force things out).
If you have done a bit of DIY before, then I think you know your Euro better than most of the fitters (unless they are Honda service tech or have vast experience on Hondas)
