How many total cursed pumpkins does it take to complete the event?

I just started playing a few days ago and I am really struggling for money. The first step for the rewards says 800, but I’m guessing there’s more than that. I can’t find anything in game that tells you, so if anyone knows and could tell me, it would be much appreciated. Thanks!

Edit: for anyone else looking for this, you need 6000 total. Thanks everyone for all the help.
