Try HPS - do a search for them online. They supply all sorts of kit including brake pads etc. I contacted them and they came back with a spec of Brembo brake pad to match the BMW OE specs, just in the Brembo packaging instead of BMW and they were helpful (I wasn't in any rush so the emails went back and forth for a week or so to get the right kit.)
The cost calculation I did at the time was that the pads they sold me were 40% of the price of the OE ones from BMW - I have used them before that purchase to get upgraded pads for a 1200 GS that had a poor back brake and they sorted me out a set of pads that were a harder material and didn't fade after a couple of hundred miles.
