For starters I would ask congress to authorize a bounty that it would reimburse any private organization that would send a manned mission to Mars and return its crew to Earth safely that would cover all expenses plus 15%.

I cannot imagine any private company that would attempt this for a mere 15% return on investment.

I could .... can you imagine how much other large companies would pay to have their corporate logos and flags planted on Mars??? Then think of advertising and other marketable factors of the landing / voyage et cetera.

You could also put all the spare seats up for bid .... Microsoft Computer specialist ... err .. Sun MicroSystems Computer Specialist. Exxon geologist, Proctor and Gamble biologist ... ad nauseum.

The return from the feds should be cost + 50% and NO corporate income taxes for 10 years for the companym (and employees) that does it. THAT would get results.

The cost of putting the first human on Mars will probably exceed the net worth of Microsft and Sun combined. People do put all of their eggs in one basket, however, the return on such a gamble must be huge to entice this kind of investment. 1,500% maybe - 15% - no way.
