To buy the discs and pads from Eurocarparts with the SALE50 code for the next 5 days with Brembo brakes and pads would cost £62.
Cheaper still if you want pagid etc.
Honda genuine parts are expensive

Shouldn’t take longer than a couple of hours at the most (Main issues I had are with the retaining screws which sometimes require a bit of persuading with an impact driver). Other than that straight forward.
Try and find a good independent nearby. But probably still be £150 - £250 region.
