Hi, I am an engineer specialized in Game development and have my own game company. I'm pretty sure I can tackle your project pretty quick if we agree on what needs to be done quickly.
175USD for the whole project sounds fine.
The game would be developed on Unity 3D 4.3 and it would be compatible to be published on iOS, Android or desktop at will.
The finished projects will be handed to you. I can't make the publishing myself because that gets tied to your accounts.
Also must decide what should be done with art assets, sound and so on.
So let me know what you think and feel free to open a chat with me here on Freelancer if you want to discuss details.
Best regards,
Alejandro
