Yo.....
Well I can enquire into getting them done for you, I'm sure it will be cheap or next to nothing, but might not be able to get them done within a week, more like within 4 weeks.
I will say green is the worst colour to do so requires the most attention, ie surface finish & prep
If we can do a "group dip" I'm sure the people I'm in contact with will be happier to oblige
Basically I pass the pieces on to a guy at work who has bits anodised for his motorcycle race team hence no direct contact with the anodisers.
There are pics of the chainrings I had done on here.
regards
Martin
