IIRC the launch cost is in the millions, but with Hubble the actual build cost, once you strip away the government boondoggles and all the added costs of the various delays etc was also in the millions, not billions.

Depending on the accounting method you use, the Hubble cost between 2 and 6 billion dollars. That doesn’t include the COSTAR mission to fix the flawed mirror, or any of the subsequent servicing missions.
I don’t think you quite have a grasp on how expensive it is to fly into space. You can’t just wave the private enterprise banner and claim that it will save orders of magnitude in cost.
For example, the Hubble weighs 24,500 lbs. If you look at this cite, you can see the cost per pound for various launchers to LEO. You might be able to use a Proton rocket, at $1697/lb. At that price, it would cost 42 million dollars just in expendible costs to lift something the size of Hubble. Launching on an Ariane-5 would cost 92 million. Building your own rocket would definitely NOT be cheaper - the costs of current launchers are as low as they are because the development costs are amortized over many launches.
The total cost of a launch is significantly more, though. For example, a Zenit-2 booster is only 1152/lb in expendibles cost, but a launch has a total cost of about $45 million.
Then you have to build the scope itself. The construction of Hubble cost well over a billion dollars. Oh, and you need launch insurance. Expect to pay a good chunk of change for that as well.
Then there’s servicing - the original Hubble needed to be serviced right out of the gate to fix a flawed mirror. But even after that, it needed servicing missions on a regular basis to replace worn gyroscopes and the like, or it would only have lasted a few years.
Servicing missions are very expensive. NASA estimated a robotic servicing mission to Hubble at 1 billion dollars. That’s what Google would have to do, unless they’re also going to start their own manned space program.
Private space exploration still isn’t that cheap. Burt Rutan spent 26 million designing and building a little one-man sub-orbital craft. He estimates that being able to build his own private orbital craft will still cost hundreds of millions of dollars. Space is very expensive, no matter how you do it.
