3D Sandbox Game to be Developed for PC

Hi there, We have the design document for a large-ish scale game developed for the PC. You will be responsible, using Untiy3D or appropriate game design software (your choice), for completing a working, polished game world that fills the following criteria (A design document will be provided for you, giving you the structure to work to): First-person Voxel-based game NPC characters that can be commanded to build, craft, fight, loiter Combat with weapons, skills and magic Very basic crafting system whereby you drop item from your inventory into a craft menu, and a result is instantly produced Gathering system whereby you can destroy blocks to add them to your inventory, then place them elsewhere later on. This will be used for town building etc. Very basic physics whereby blocks tumble if there is nothing supporting them The basic premise of the game is to command your followers to build a town/castle, and defend that castle against invading armies (no more than around 20-30 enemies will close in at any one time) You can also go pro-active and recruit followers to follow you into battle. There are plans for more features in the future. Multiplayer is one of them, both local and online. An added note, all 3D models, textures animations and Musical effects will be provided for you. User interface graphics and what have you, however, are not. You will have to implement these as you go along, in keeping with the game's art style. You'll also be responsible for ensuring that the game is kept very close to the original design. Now then, we're not looking to start this project for another 30-60 days, and is based on us being able to get funding so get your bids in for considerations, because you're nothing to lose by bidding, and a potential large project if we get it! A quick note on programming: I'm no programmer but I'm aware that for voxel-based games, you need to be able to code in a custom system within the game engine to handle 'voxel containers'. This helps to reduce lag in game by obscuring blocks that cannot be seen, therefore they are not rendered until the block is exposed. That's about my limit on knowledge of programming. I also have little knowledge of just how much work will be going into this from your side, but don't price yourself out of the job!
