Judging by the time of the post at 4am this was either insomnia at work or you were in another time zone on holiday.
Any good prestige bodyshop or car restoration place can refurb the calipers.
Estimate for the 996 Turbo came to around £1000 for all 4 calipers to be reconditioned with Porsche new seals etc, resprayed and lacquer, inclusive of removing by an indy, courier to refurbisher (e.g. pro-calipers), courier back to indy and indy to refit and bleed brakes.
If one can DIY then it saves the indy fee to remove and refit - around 3hrs labour. Typical indy labour rate of £80 + VAT /hr = shade under £300 saving.
