I am a professional unity game developer and manager working this area for 3 years.
I developed lots of mobile unity games such as mobile car race game, mobile poker game and so on.
I have 3 co-workers and they are very talent. We developed lots of server-client multiplayer games such as online poker game and mobile hiking game which uses the java, C++ server, mysql DB and unity client part. My team have a java poker server code which my team developed earlier so I think it is a very essential for both of us to do this work together. If you have low budget, I will agree with your financial opinion. I really hope to work with you for a long time and make success business for both side. I like deep trust relationship more than anything. This kind of relationship helps both sides to reach the goal.
I do care about the quality of my work, not the quantity of payment.
Please call me, or inform me whether you choose or not! Thank you!
