There is Dr Lisa O'Connor in Stirling, N.J at 908.647.1688
I personally go to Callen-Lorde but I've heard good things about Dr O'Connor. However, Callen-Lorde or Mazzoni Center is going to be significantly cheaper.
As far as non HRT doctors go for general healthcare, the Summit Group which have offices across the state are transgender friendly. (Mine in Clifton, NJ has been excellent to deal with.) Just google "the summit group nj" and it will come up.
