If you want to go for a cored device, I would recommend Sowter in the UK for a custom unit on a 100% mumetal core. I'm not sure what the delivery time would be though.
You would definitely need to filter the LF before it hit the output stage if going for a mumetal core. The other thing is that these cores with large gaps can sing along to the signal, so you may wish to try and cure some resin around it if it becomes an issue.
If you decide to go for an air-core - well, any transformer winder should be able to wind the required bobbins for you. I'd proably go for the air-core myself...
good luck,
