Does my band have enough equipment?

If you are playing in huge venues then you would have an idea of what you need to set up from playing small shows first then working your way up from there cuz no one can just get a huge gigs right off the bat plus big venues have to-noch PA systems and mics and all that **** and if your not bullshitting i would like to know how you are getting all these big shows when it seems like you dont have the experience to earn them.
