Good custom coil supplier?

Question

Does anyone know of a good custom coil supplier in the US?

I need some small (40mm OD) air core coils wound. It's an 125 kHz RFID antenna. Say, either 2.5mH or 750uH, exact value and DCR negotiable and TBD. I'd like 5-

10 protos to test and tune with before ordering the first production run of 500. (I'm in a bit of a hurry, as well...)

Here's an example of someone else's similar design:

dWe've used Warner Electric, with a coil winder named Sue, but I thinkshe's only part time now.  Ten does not sound like enough to getstarted. (But you can always ask.) Maybe wind some yourself to checkthe design.  Get some forms made and a lathe (with a back gear) towind them on.George Herold
