What's the best theme / plugin to use for a website for hunting needs, destinations, outfitters, lodging, etc.

We’re building a website for a client that wants to be the premier destination site for hunters to find lodging, destinations, gear outfitters, etc. They have thousands of listings ready to import. I’ve seen one plugin that we’ve tested that did everything, including billing, payment gateway for premium listings, included inbound forms that created the listing, ways for users to design their listing with a page builder, etc. But it’s under developed and not scalable. Any suggestions?
