White Knight and Stretched White Knight would be a problem for amateurs, but SS1 would be a task worthy of the effort. You should be able to build an EZ-SS1, and transport it to the Mojave Spaceport where the White Knight could be hired by the launch. Not cheap, but what use is all your money you've been squirreling away for a 4X4 you won't be able to get gas for anyway?

Not quite your average garage project, at least not yet.
