I am an experienced XBox/PS4/PC developer, having authored or collaborated with several indie games, both in development or developed for all plataforms. 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.
I own devkits for XBox One and PS4, since I am a certified developer for both, I have a steam publisher account with access to steam SDK. For my budget, you not only take me, but also a veteran game-designer, a outstanding concept/2D artist and award winning audio composer.
As for the milestones, I propose a kick-off fee of 30%, after that payment is cleared, work starts immediately. Roadmap and further milestones can be adjusted after the project plan is set.
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.
