Hi Nick,
Thanks for reaching out to us and welcome to our support forums.
Hopefully you can do both! First create all tickets for the event: early bird, after early bird and at the door ticket. Then set the ‘Start Sale’ and ‘End Sale’ dates of each one accordingly. To show the tickets not available yet, and the remaining stock in the event you’ll need to override the ‘tickets form template’ with the customized version I provide you below.
To do so create this file and folder structure in your theme folder ‘tribe-events/wootickets/tickets.php’ – for more info on this please check out our Themer’s Guide. Once you have that file in place, please paste the code below in it and save changes:

That should do the trick for you, please try it out and let me know,
Best,
Nico
