Hello
I am experienced web application developer, see my profile for the samples of applications developed by me. I ahve proven to be one of the best in the TopCoder software design and assembly competitions. See my profile at TopCoder, the link to it is in PMB.
I can get your project done using Java EE technology, it is much more flexible and efficient than PHP.
I can get you a team of 3-5 developers, act as their lead and get your project done efficiently.
Price is negotiable, once we come to some particular details of what you need, as knowing that you need just similar game is not enough, we need to write up exact requirements.
Thanks for attention.
I am looking forward to work with you.
