Functionality of spaceship that shoots automatically. UE4

I'd like to pay 27-40 USD. Due date: 2nd January. There is a turret. I want the turret to rotate and fire on enemies. The last are basic spheres, that moves. First enemy moves back and forward, second left and right. The turret(shape is basic Cone) momentaly change rotation to the closest enemy(look up to the center of the sphere), and do shoots. The turret shoots automatically. The bullet is shape of small circle. If the bullet hit the target, print a message. Bullet moves straight on direction it was send, and doesn't change it FoV (Field of ​​Vision) make variable easy to change in the editor. FoV is not limited by distance, but it is limited by degrees(or radians whatever). For example, FoV is 180 degree, the Cone have to shoot at enemy if it is in front, and don't look at it if all enemies are back. if FoV is 90 the turret won't see anybody who is left or right. if there are no enemies in FoV, stop shooting, and don't rotate. If an enemy apear, rotate to him(momentaly) and shoot while it is in FoV. Also, there is another type such as Friend. Shape is a cube. Don't shoot at him. If friend is between enemy and the turret, shoot to another closest enemy in FoV, or don't shoot at all(but keep rotating). If enemy appears again do shoot at him. To sum up, there must be a cube type of friend, 3 enemy, and two cones type of Turret. Two that moves and one that turret doesn't see and if I change FoV, the "game" must work properly. P. S. Size of turret is ten or twenty times smaller than ordinary basic sphere. Size of bullet is 15 times smaller than size of a turret. It must support up to 100 friends, enemies Using BP or C++ is up to you. Don't matter if the sphere moves with or without acceleration, do what's easier.
