Assistance SELECTING a wordpress directory theme (ADVICE - NO CODING) 1-2 hour consultation

I am looking simply for advice/recommendations from someone that is familiar with wordpress directory themes such as: [login to view URL] [login to view URL] [login to view URL] I essentially just need help SELECTING which theme would best suit MY needs and has the best coding that can easily be modified by developers to add additional features. Also, SEO and responsiveness is of importance. This job could lead to more work (which will be posted as a separate project) such as: - adding new payment gateways - adding featured posts - adding advertisements that can be managed through the backend and frontend by the user - modifications of the users front end - creating invoices for listings/advertising - and having them stored in the users front end as well as sent automatically to their email - modifications of the directory listings (add/remove fields for text, pictures, documents) - etc.
