There we go, that clarified some things.
If $48k is within your price range, Tickdata.com will be providing some of the best and most historically accurate data you can purchase.
As you have noticed, there are virtually no companies out there that provide high quality historical tick data for several decades and maintain live tick streams for equities. The infrastructures for providing these two services are very very different, therefore most companies are much better off providing either one or the other.
Now, if you're operating on an enterprise budget, you can look at the high end alternatives. Reuters can deliver historical tick data and live streaming data. Go from here if interested:
