Little Project Unity

I would like a budget for my project Unity I need to finish 10 of the 14 items below: - Create a scene with 3 zombies that walk through 3 different waypoints between them. - Create a character called Player that should be chased by zombies, if it comes too close. - Each zombie should have a bar of energy that represents his life. - The Player must also have a life bar and must move through the keyboard inputs. - If the player is touched by the zombies should be shortened his life, if he is touched 5 times by the zombie he must die and a message of GameOver will appear to the player. - To defend against the zombie player must have shots and mines, initially the same will have 10 shots and 3 mines. - For the zombie to die the same must receive 4 shots or be hit by a mine. - If the Player kills all the zombies, a message of Congratulations to the player should appear. - The Scenario should have items for the Player to recover their shots, mines, and energy. - The mines have sound for explosion, particles instantiated when exploding and that it is destroyed when activated. - Player shots are instantiated the moment the player presses a key. - That when being shot by the zombie, instancie a particle of blood and that when touching the Player the same also instancie particles, of blood. - Zombies must "drop" items that can restore the Player's life or even be new weapons with which they shoot different projectiles. - The Scenario should be created by the group with objects modeled in 3ds Max.
