Skip the PPL and go find a 141 school that does a CPL add-on. The minimums on some of the approved courses some 141 schools have make it quite reasonable to get the CPL add-on even if you only plan on doing personal flights - so why not get the CPL.
I had a CPL(A) and went and got a PPL(H) addon and then upgraded to CPL(H) part 61. Took a total of some 75 hours. A 141 school had an approved course for a straight CPL(H) addon for only 50 hours - to bad it was to far away from me. THey have similar courses that go the other way.
