full online course

Hey beautiful people, i'm trying to start learning german and i'm aiming to hit b1 by the end of the year, however, courses in Berlin are becoming ridiculously expensive, and their classes times also doesn't fit my schedule, and as great as all the sources here on the Subreddit...

i was wondering, is there an online course or a website that i can purchase or maybe subscribe to, that has everything at the same place, and can be an alternative to going to a school or learning with a private teacher, i mean, if i'm paying 250 euros for an a1 course, i might pay 100 to get a course that has everything in it and that i can start whenever i want.

Thanks a lot
