Spraying a cup spoiler LY

I've recently bought a cup spoiler to replace my Ktec one. However, I've been to numerous body shops in my area and they all refuse to work with liquid yellow, saying it's too complicated to match properly. Do you guys know any places that will be able to help me in the Oxfordshire area, or companies that can come to me? I would send it off to sprayshack, but I need some holes in the tailgate filled and sprayed and can't exactly send them my whole car! Also, what would be a fair price to pay for spraying the spoiler? cheers!
 
Good question I suppose it's down to where you take it but would have though £100+ now 5 years ago when I had mine done it was £50 at mates rates
 
yellow is a notoriously bad colour to colour match.
The old leon cupra's of which i had one, used to have slightly different shaded panels, even from factory cos its such a bitch to get right.
