Agreed but rude.
That is a lot of work and pressure for someone doing this for absolutely free. The 15day deadline is what got me, I'd recommend adding some form of payment or concrete incentive. Even if you can't pay much I'm sure a lot of creators on here would be willing to work something out with you.
If that doesn't work then learning how to draw would be helpful. If your like me and it just isn't a thing for you then I would go the prior route or be more flexible in what your looking for.
