football design

I am looking for someone who can: 1. Build a Football Stadium Environment in Unity 2. It's a builder mini game where user can upgrade the stadium. 3. Make every stand and corner of the stadium expandable/upgradable.. from samll to medium to big to ultra large ranges with different stadium models. 4. Show capacity of each stand 5. Show the cost of each stand 6. Make a UI where user can preview stands before placing them. 7. Make an animation when upgrades are done for (amount of time) 8. Make this mini game in a seperate scene that I can load from my MAINGAME, this will be a mini game in it. These are important point, maybe after discussing there will be more points, I hope you get my idea. I have a example of a non optimised environment showing this mini game that I would like to create. See that you got some experience, I want to buy more assets that we can model so that every stadium have a lot of options in capacity and different price ranges... The stand of tribune are just like in a real; stadium 1. Small stadium (Single stand, options for roof or not) 2. Double stand (stand, options for roof or not, more capacity then single) 3. 3 ring stand like Barcalona Camp Nou has. (this will be the biggest stand) 4. A ultra large 4 ring or stand Also a option for a complete new stadium should be possible. Prefereable we would like 10 different stands for each size and for each model different capacity. Also the short stands are lower capacity offcourse. And corners to lowest capacity. When the user make adjustments to the stadium animation like a picture I have included with cranes and workers working on the stadium expansion is a must. I think it's easiest to have a city in the background but to focus ONLY on the STADIUM, TRAINING GROUND, and STAFF FACILITY. meaning the city serves as background, but I do want to be able to build more models in the city background if needed. Well anyway, I hope I explained it good, and if you need to know anything please ask. Here are some pictures to give you an impression. (PICTURE 4.jpg illustrates the aspect when user has upgraded then it will animate with a construction scene around the stadium, trainingground or staf buildings.) PICTURE MyClubGround.jpg shows my project in unity, where I started to build on my idea.
