Make a Unity 3D Tower Defense Game

**Only respond if you have experience with Unity. Please post a link to an iPhone game that you have built in Unity.** I am new to Unity, but would like to make more games on the platform. I have found a bunch of cool assets on the Unity Store (some for game logic, some for graphics, and some for realistic camera/environment effects). Could you please advise on whether we can combine these elements to make a Tower Defense Game in about 1 week of work-time? If your work would involve a lot more than just combining the pre-built elements, if you give some explanation about what other work is involved, I am open to allowing a bigger budget to provide for additional work time. My goal is to find a solid Unity freelancer who I can work with on a regular basis, 20-50 hours per week. Ideally, I would like to build and release a new Unity 3D game about every 2 weeks, just by combining elements from pre-built game templates from the Unity App Store. If you would like more details about the Tower Defense Game I would like to build, please see the project brief attached. It includes links to the assets from the Unity Asset Store that I would like to combine to produce this game.
