Hi there,
As you know that Uber is a very huge App, there are lot of features in it, so let me assure you that we can deliver this project successfully and I do not see any technically hurdles but your selected budget range is very low. Our bid is just a placeholder to submit the proposal, as we cannot submit proposal without entering any amount and once you show some flexibility, then I will give you our precise estimate.
Look forward to hearing from you.
Regards,
YK
