Help with painting grill surround

Hi folks,

I've had a look through some threads on here and there seems to be some mixed info so was hoping I might be able to get some clear instructions. 

I want to colour code my grill, I've done the bath and separation bit and got the centre badge off. I've then rubbed it down so I now have a sort of satin chrome finish as it were. This is my second attempt at this, I got all the way to the lacquer stage last time but got a big blemish and it all went wrong so I've rubbed it all back again.

Last time round I used Halfords Bodyshop primer, matched paint direct from Skoda and likewise the lacquer that comes with it. 

Now I'm at the rubbed back stage, if I go at it myself, what primer should I be using, paint will obviously be the same and the lacquer but not sure which primer to use.

Alternatively, I'm in Hertfordshire, is there anywhere that could do the paint job for me, anywhere I can either take it or send it and what Wayne would they want it at? Would they want it primed?  In which case refer to question 1

Many thanks,

James
