Build Landing Pages from Custom Pages + Accept Payment

Enable the creation of landing pages from custom pages with the option to set any landing page as the main home page. The directory owner can choose between a landing page or a listing page as the main home page. This feature will support building membership sites. Additionally, the landing page should be able to process payments (one-time or subscription) to grant access to the main directory, functioning as both a sales/info page and a paywall.
