I think this should answer you:

I had a look at the clamps, and they are seriously expensive! about 100$ while the board costs about 20$ ... so that's a no go :-DD
What if I want to get some sort of plastic clamp manufactured with some copper inserts embedded in them? this is a product that I plan on selling so I can get custom parts made if they're not 5x the price of the product itself :-+

As I mentioned, I will be building a very similar device using pogo pins. I might post an update but it'll be a while.
I seriously have no idea why they are so damn expensive. I'm guessing they don't sell like hot cakes? which can be explained by their price? it's one of those circles ... with injection molding they can be made for less than 10$! there isn't anything inherently special about them.

They're not that dear from member Franky's shop:

You can probably get them cheaper from some unknown source but Franky stands behind his products.

I bought a pre-made Kelvin clip set from Pintek when I was getting some stuff from them and the build quality was excellent but the choice of cabling to the clips was not. I moaned that the short leads between the wings of the clips needed to be of quality flexible cable not some stiff PVC insulated muck which they took onboard to make changes in future production. I'd not buy any pre-made Kelvin clips again without handling them first to check cabling.
