Good custom coil supplier?

[Scott Newell]

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:

How do you pronounce Chrysler in Italian?... "Crapolitano"

We've used Warner Electric, with a coil winder named Sue, but I think
she's only part time now. Ten does not sound like enough to get
started. (But you can always ask.) Maybe wind some yourself to check
the design. Get some forms made and a lathe (with a back gear) to
wind them on.
