Hello
My name is Aurang Zeb
I definitely understand what you need and I can do such app.
Everybody can do it , but I know how to do it and avoid common mistakes which eat much time and delay timelines.
I agree with your cost of this task and even can do this in two times less, because I am interesting in long -term projects and want to show that I am reliable, can do job quickly and with high quality.
As I have great experience in mobile development you can easily contact me to get any consultations to evaluate how good I am in this field.
It was nice to offer my knowledge for your job. Thanks
