Trying to plan 21st

Hello everyone,
(Appoligies if im using this app wrong never used it before)
Basically my 21st is coming up in September and I need some recommendations on what i should do.
Basically i only have a few friend so dont think it would be a big turn out but wish more people would come.
I want to have one of those cool 21st you see on instagram and get drunk and celebrate but idk where. Was thinking going to clubs to keep people entertained but want soming cooler and more sentimental at the same time like a space to drink and share photos and speechs . Idk if that makes any sence but like a function before hitting the clubs. But im also a student and have like no money and nor do my friends so cant afford much. And dont have a big enough house to have it at home.

Anyone have any ideas in what i could do?
