Plugin for regestering and booking

Could anyone recommend a plugin for me please? I’m looking for something I can use to do the following

-Allow people to register their details on our site with custom fields
-Set up groups with limited spaces and allow people to sign up to them
-Create easily accessible and exportable lists of registered people
-Send automated emails to people who sign up to different groups
-Having the potential for payment integration would be handy

I’ve had a search but am not too sure on any I’ve seen and don’t want to buy anything that doesn’t do what I need. Thanks!
