Hi there.
The common practice would be to make a blogger account and set that site to be an example for your Adsense account. It would be an easy and fast solution for this case and would get reviewed faster than some other websites, and that is just what you want. Correct?
Also, when do you plan to start this project, and do you have a specific deadline?
Anyways, feel free to hit me up so we can talk more about this. I am very responsive. All the best
