Camps registration + CRM + marketing

I need a plugin which will allow me to do the following: 1. Define camps - as custom post types - have additional custom fields (start_date, end_date, price, discount, end_date for discount, end_date for registration, etc.) - duplicate camp functionality - should be able to see how many registrations I have - have the possibility to manually add a new registration using the admin dashboard - should create a template for the camp custom post type in which the camp is displayed publicly (will contain camp information: price, available slots, time, resources which can be rented, etc.) 2. Define registration forms - these forms will be used on the public page to allow registration to a specific camp - be able to define custom fields which the customer (person who wants to register) has to complete - custom fields: e.g. should support date selectors (good UX for selecting birth date), checkbox groups, etc. - same registration form could be used for multiple camps - submitting the form is possible only after registering on the website (has to be tied to a user) - when submiting the registration form, a new post (cpt) is created which represents the registration - I would like to have some autogenerated forms, but I would like to be able to customize them and save (also import / export) - possibility to have multi-page forms (split the registration process on multiple steps: e.g. payer info on a page, participant info on another page), any number of pages. - if the user has already registered to a camp, allow him to use the same info when registering to a new camp (in case there are differences, ask for differences) e.g. prepopulate the form with the previous data for address, telephone, etc. - e.g. I want to be able to show that for a specific camp people can rent equipment (bikes, skies, snowboards, ATVs, etc) 3. CRM - focused as any other CRM on users - add private comments (details, e.g. it's paying on time, it's not paying on time, it's causing issues, etc.) for each customer - should be able to see on how many camps a user has registered - should be able to integrate with MailChimp to send newsletters to a selection of users - search / filter by different tags - search / filter by different camps - show all people which have been registered to a specific camp - some basic invoicing system (generate an invoice after the user has registered and payed the registration: online / offline pay) 4. User dashboard - see on which camps I have registered - see details about each registration (camp details) 5. Social login - ability to create / login using google / facebook / twitter 6. Online payment - add the possibility to pay online Other details: 1. everything should work with polylang - be able to create different language versions for each camp - be able to create different language versions for each registration form Before starting the project we will provide a more detailed description of each feature and some videos on the way the current system works (it's been developed over the years in different technologies and we want to bring them all together under wordpress)
