Hi,
I can fulfil your requirements of Game development. You can review my work from my freelancer profile which I have been doing for a Game Studio. Based on my work experience I’m proposing the following terms:
I will work as a game developer and will provide support for one month after the contract is ended, and I will charge 384$. Please note that the time and cost are negotiable.
My services also include google play, achievements, cloud save, facebook leaderboard, and ad network integration.
Looking forward to the discussion of requirements, so that we can set our timeline and start working as quickly as possible.
