Hi ,
If Location will not be a big constraints for you, than i can say this proposal is for you.
I have gone through with your project post. and time and cost estimation would be depends on the functionality and UI Design ,So its hard to say about it. But i have quoted maximum budget.
WE are a team of experience mobile app developer having more than 5 year of exp in it.
Please initiate PMB to discuss further so that I can clear some of my doubts and can understand complete scope of work and provide you inputs to get the things work for you as you expected.
Looking forward to your response!
Regards
