Any subscription-served HF remote bases in the SoCal-AZ area?

I'm intrigued by the prospect of participating in the new microwave/Cactus discussion net starting up on 40 meters, but I have concerns about causing RFI to my neighbor's PCs, WiFi and broadband internet devices.  As a possible alternative, might anyone know of a subscription-based HF remote base service available in the SoCal or AZ area?

Thanks!
