[VoiceOps] Wholesale Orig Provider with Low DID MRC and LNP Fees

What nationwide providers offers DID's at a true wholesale rate? I am looking for something $0.25 per DID and under, and LNP cost of $5 or under per port. Am I asking for too much? I know Verizon has a SIP origination option. What about AT&T, Sprint, or T-Mobile? They seem to be on-net in most all markets due to their cell phone entities.
