Insurance sought for beginners (SF 0)

Hello, I am looking for a cheap insurance for beginners. Since I have only had the driver’s license for 6 months and no one I can insure myself with I catch at SF 0 100% or 95%, now I am looking for a liability insurance to get at least the first 2 – 3 years into a lower damage-free class. Originally I wanted to get to the ADAC which was in ECO tariff quite cheap, has branches everywhere etc. The problem was the 1st year SF 0 with 100%, in the 2nd year SF 1/2 with 95% and in the 3rd year SF 1 should be with 79 %. That is quite expensive for a beginner.
