How much roughly and where in the UK could I have a mould taken of my bumper, now I normally make all my moulds but no sure I feel confident making one from this.
Thoughts on how hard it would be?

Plenty of places here in the uk that could help. Biggest thing will be your budget and how many parts you want to make and in with what process?
From a squint on my phone i reckon there wouldnt be too many splits and possibly a couple of inserts for the lights.
Where are you located?
