Basketball shootout game app - repost

(Bid if you have experience with game development and have a portfolio.) Looking for a game app developer to create a game similar to the one below: [login to view URL] Differences: ball has to bounce realistically like an NBA approved ball (the ball in the sample is like a sandbag), the size of the rim vs. the size of the ball has to be similar to real life proportions (not cartoony), interaction between the ball and the rim must be realistic, the aiming points do not link the ball to the rim when the player is aiming. The aiming points appear below the ball only (indicating the inclination and the strength of the shot, similar to the Angry Birds shooting style). The ball floats in the air the same way (waiting to be thrown by the user). The shooting distance changes randomly after each shot (it doesn´t stay in the same place). It is intended for 1 or 2 players. Each player gets 12 shots to complete the goal and get a reward. The reward is that a locked picture will be earned for collection and visualization by the winner (visualization inside the app in the user´s private collection). If player 1 misses one shot, he is asked if he wants to risk a 2nd shot. If he chooses no, game over, he enters simple PRACTICE mode, with no goals, (in case of single player), or player 2 will shoot (in case of 2 players). There are 10 different rewards in the game, each obtained after 12 shots. Game: You get 12 shots, and you see how far you can get. If you score all 12, you complete the goal and get a reward. If not, you get as far as you can (get a partial reward according to your progress, not full reward.) Practice mode: no goal, just for practicing the shoots. mode 1: you get 12 shots, you can save your progress up to the 6th scored shot. you can risk. If you lose, you return to your saved shot (6th). Get a limited reward because you are able to save progress. mode 2: you get 12 shots, you miss and you´re given another chance (you risk). If you miss you start from 0 again. You get full reward because you are not able to save progress. mode 3: Once you complete mode 2, you can get special rewards if you complete 6 straight shots. Requirements: the rim, the ball, the shooting physics, public licensed music for the background, background is an LA beach (a public basketball court in front of the beach), the sound of the ball when bouncing on the floor and against the rim. You will be in charge of coding the basketball shootout part of the game. In case the player makes the shots, he will get rewards. Rewards will be planned at a later stage, but the job is to complete the basketball part. The app is going to be posted in Google playstore for some cents. COMPATIBILITY WITH ALL SMART PHONES is wanted. Best regards
