I am going with a yes, and hear is why. If person A (The Costomizer) is hired buy Person B (The Client) to do the work Person B is providing the kit only. Person A is doing all the work to the best of his ability, it is all person A's skill and all of his work, Only kit was provided by person B. If the model turns out particulay well than person A should be alowed to enter HIS works, But person B should never be alowed to enter a comission in a contest. That is just how I happen to look at it.
