Hello,
I am a graduate student of 3D animation and modelling program and know the process of creation of the task that you require to have done, and looking at the project budget I wonder if you, sir, indeed have understanding of the real cost of such a project. I can tell you that 50GBP is not even a close price.
Just for comparison, imagine that you are providing body of a Tesla car and are asking to put inside of this body all elements of Tesla for the price of one or two Tesla's wheels.
I am bidding on this project just to see how this project will expire in 6 days with no freelancer chosen, or to see this poor guy who will be ready to add all the elements of the car for the price of two wheels of this car.
