Java developer for WP

hello i need to modify/expand my calculator on the web: [login to view URL] We want the calculator to have more options same as it is on [login to view URL] we want a copy of the solutions we got in regular rank boosting to our ESEA boosting. So ideal copy of that calculator but with different ranks because esea has different ranks. so the ESEA calculator will need new features such as: - 3 boosting types 1) ESEA Rank Boosting On website actual calculator is esea rank boosting for the pilot option we want to add here self-play option where self-play is % of the price from a pilot. Same as it is on regular rank boost calculator. Moreover on self-play mode maximum rank we can deliver will be A-. 2) ESEA Boosting per Wins Here same as it is on our rank boosting calculator but ranks from ESEA and on self-play mode maximum rank to buy wins for A-. On pilot no restrictions. 3) ESEA Placement Matches same as it is on rank boosting same copy. same payment method as it is, same ordering forms all the rest stay the same as it is. so in theory we want ideal copy of our working calulator to use it on esea with ranks of esea. It's all on WordPress working with our ordering forms etc.
