Application based cms for laravel

i am writing an Laravel application. this application needs to a CMS.

my application have something like user membership,newsletter emails, authentication,advanced searches etc, depend on posts. a CMS can not handle my application alone. i need to a extendable CMS that resolves my requests.

i saw October CMS gallery and i think it is for blog or simple sites not an extendable application.

what extendable CMS or package (in laravel) can resolve my requests?
