I am an experienced Unity GearVR developer, having authored or collaborated with several applications for 360º vídeo visualization and VR games. I have been working with clients all around the world for years, I'm used to self-manage and to articulate with different time-zones.
As for the project, I already have the infrastructure for 360 visualization you require, so, my work will consist mostly on UI+Image streaming implementation/development.
As for the milestones, I propose a kick-off fee of $1500 USD, after the payment is cleared, work starts immediately. During the first week I will provide you with daily updates on the project+screenshots (if required).
On day 5 of the project, I will send you a intermediate release for testing, after the payment for the second milestone is cleared.
During the second week, daily updates continue up until project conclusion. On day 10 of the project, we have the final milestone and I'll send you the final delivery after the payment is cleared.
