Twenty two months seems like a very short time to build a brand new political party from the ground up. However, if you start with the Libertarian Party, and merge all of the various Tea Party organizations in to it, with the LP’s existing , very effective infrastructure, you automatically get a huge head start on the process (as per SpeakerToAnimals suggestion). But it’s still a very short amount of time, to build a new party.

Sorry, the libertarians want to force the legitimization of things I oppose to the death.
