Use landing page without making it home page

Hi. I have created a new site and need to setup a landing page. None of the plugins I have tried are doing what I want. I want the home page to be the home page rather than making the static landing page the home page. I have created the landing page, but can’t figure out how to get it to work the way I want it to. Any help would be very much appreciated. The site is elevationscm.net. The homepage is the way I want it to stay. elevationscm.net/landing is the page that i would like to use as a landing page.

Thanks for any ideas!! MaryJo
