If you are serious about getting a portrait lens then you need an f2.8 as a minimum. The 135 is good in both Canon and Nikkor. 70-200 f2.8 is also good and both companies supply them. There are some older f2's getting around but really anywhere around 135-200 at f2.8 or lower is what you need. Image stabilisation is less necessary but most gear now comes with it.
Do not buy an f4 lens. Yes they are cheaper but portrait work needs fast sharp lenses. I guarantee you will not be unhappy with anything under f2.8. You are gonna spend more money but better images come from faster lenses.
