Detailing stickers on vans

Si Jo Tom and Ems

Our 550/6 Ranger is quite tidy, but since a 2006 lady the stickers are starting to look a bit aged. I thought It be nice to refresh them.  

How expensive can they be?

We have the bubble ones, so I need one each side at the front, another big one at the rear and two smaller ones on the sides at the rear.

I have just been quoted £444.14 fitted !!

Has anyone got experiance or guidance on this since the price I am being quoted is shocking!!
