Documentary: The former Neo-Nazi who became a Jew

My name is Yan and I'm fundraising to finish a documentary film I started in a class at Reichman University in Israel. The documentary is about Yonatan Lutz Langer, a former neo-nazi from Germany, who left the extreme right group and later converted to Judaism. We already filmed all the footage for the film, including a visit with Yonatan to a concentration camp in Auschwitz. The money is needed to hire a professional editor and for all the post-production expenses. My goal, once the film is done, is to approach film festivals, tv channels and streaming platforms so the film can be seen by many people. I believe Yonatan's story is inspiring and hopeful because it shows that intolerant, hateful people can change and that it's possible to overcome racism and antisemitism. Thank you for your help!
