Hi sir''
I am agree with your MILESTONE AND I CAN DELIVER YOU WORK IN YOUR TIMELINE and BUdget.
Dear sir I want to suggest you that if you are going for long term and quality work please don't go for any cross platform App because you know that cross platform App always crashes after some time due to heavy script and needs heavy maintenance.
So please consider for Native platform as you will need best quality work with zero maintenance as well as easily customization in future updates.
