The name can wait, identify and outline the tenets first. Then get out in the community and campaign, asking people if they agree with "xyz" principles, and many will because this would be a strictly rational and fact-based party, no nonsense. Gain rapport and support and find someone good at raising money. You need a website and advertising. Then you need a candidate, it can't be you. Someone that's good on camera with a clean background who can speak off-the-cuff and answer tough questions quickly. There's a lot more but there's your homework.
