Hi sir,
We have a complete solution for your project and have worked on all the functionalities that you have listed like add new taxi, new permanent customers, drivers, new accounts, people can log in or register to book the taxi by different sources. We have implemented OTP generation for Pickup and drop as well. I can share you the APK of the app once we meet in chat, so that you may get a clear idea on our work.
Please ping me to have a look at our work function on Taxi app.
Thanks and Regards,
Neeraja
