Selling taxi operations or how to continue?

Hello, I’m pretty new to this area, so I’d like to know your experiences and not be mocked. Last year I passed the test for a taxi operator concession and since then we have registered a taxi concession in Hamburg. In advance: I made the concession rather for my father, I don’t drive myself (not to mention that I have a taxi license). Everything runs on my name and just does my father. Like you The taxi covers only moderately the fixed costs and in case of greater damage of the vehicle we would probably fall into total failure. Now you could say: wrong calculated, driver is bad etc. We would also like to try it with a night driver, but now I am afraid that everything can go backwards. Also the idea to sell the taxi operation completely (with But I don’t think it’s relevant in Hamburg or is it worth it? Can you run the company as a family company somehow? Since we are currently regulating it so that my father gets 50% of his rides out and the rest, the fixed and variable costs are paid. Somehow this doesn’t work and that I always have to pay for my job for the taxi which is not in the sense of the inventor. I’m quite a uf the hose and sometimes apart from the stress in the family, I am already quite annoyed by the whole business. I was told that also 3 drivers should drive. If you drive father during the day, then for a week would be mo-fr for a night rider and on the WE for a night rider. But is there any night driver who drive only during the week? As you can see, I am quite inexperienced and on advice and tips I would be very happy. MfG Garojan
