Hi,
Hope you are doing well,
I have seen all the prototypes thorough the link shared and They has nice UI design. I can build an android app with those prototype designs if shortlisted.
Technologies I would use,
Java, Android Development, Optimized Libraries, Google Map API's.
In past, I have developed various design from the UI/UX design shared by clients and looking forward to implement those design for you as well. Budget quoted is negotiable.
Thanks & Regards,
