Used to hang out on Will Zachman's Canopus forum, using an off line CI$ agent called 'Golden Compass'

Apollo 18's Saturn V was used for Skylab, and the last one ended up as a lawn ornament

The prizes would be graduated, with a goal of creating a sustainable infrastructure [but it is possible that a given prize could entice a 'one shot' effort like Lindbergh's ocean crossing. The prize list [and discussion] was posted at Getting to Space:Prizes

I can solve the space access problem with a few sentences.

Be it enacted by the Congress of the United States:

The Treasurer of the United States is directed to pay to the first American owned company (if corporate at least 60% of the shares must be held by American citizens) the following sums for the following accomplishments. No monies shall be paid until the goals specified are accomplished and certified by suitable experts from the National Science Foundation or the National Academy of Science:

1. The sum of $2 billion to be paid for construction of 3 operational spacecraft which have achieved low earth orbit, returned to earth, and flown to orbit again three times in a period of three weeks.

2. The sum of $5 billion to be paid for construction and maintenance of a space station which has been continuously in orbit with at least 5 Americans aboard for a period of not less than three years and one day. The crew need not be the same persons for the entire time, but at no time shall the station be unoccupied.

3. The sum of $12 billion to be paid for construction and maintenance of a Lunar base in which no fewer than 31 Americans have continuously resided for a period of not less than four years and one day.

4. The sum of $10 billion to be paid for construction and maintenance of a solar power satellite system which delivers at least 800 megaWatts of electric power to a receiving station or stations in the United States for a period of at least two years and one day.

5. The payments made shall be exempt from all US taxes.

That would do it. Not one cent to be paid until the goals are accomplished. Not a bit of risk, and if it can't be done for those sums, well, no harm done to the treasury.

I had Newt Gingrich persuaded to do this before he found he couldn't keep the office of Speaker. I haven't had any audiences with his successors.

Henry Vanderbilt points out that having a prize, say $1 billion, for the second firm to achieve point (1) above will get more into the competition, and produce better results. I agree.
