Browser game needs built

Yes I need a browser game built it will be a mafia game I will need the programer to be able to design and write coding i also will not pay all up front i will pay some after each quarter of the job is done. meaning when ur a quearter way dne i will add a quarter of payment to milestone when ur half way done i will add another quarter when ur 3/4 way done i will add another quarter then when ur completely done and the game is packaged and ready to be installed i will add the final payment and then once you install it i will release it unless you prefer another payment method. I am very flexible in this but send me a pm if your interested thank you
