Hello,
Donna Coupe in the UK (donna@dcoupe.fsworld.co.uk) does very nice stickering. I have worked with her on several occasions, good quality and quick.
She offers via her ebay-shop complete sets of stickering for e.g. Alitalia, but the best thing is to paint the stripes and sticker the lettering.
Give her my regards when you decide to contact her.
Yves
