Hey
We are a team of seven CS Graduate in Dhaka,Bangladesh . We deals Mobile app based projects. In your app I think there will be four Major pages,
a/ Login /registration Page
b/ Agent Dashboard & Listing Page
c/ Customer Dashboard & Search page
d/ Contact & user to user chat.
We can do it in two weeks(04 days to design & 10 Days to develop), and for user to user chat our choice is to use google firebase.
Our development charge is 12,000 and deployment is free .
Thanks
