For a domain sales business, what is the best way to create and manage about 500 landing pages, each connected to a top level domain name?
I have worked with the Domain Access module in the past, but that becomes very unpractical with more than 10 domains, it lacks the features to handle large numbers of domains.
I have worked with and Aegir server but don't have experience with using a shared Drupal commerce instance for all the domains.
The domain landing pages can either be one page or multiple pages (sites) as long as it will be easy to apply different themes to them easily, if possible through a centralized management tool.
