Agree. That's a major project. I suggest you do indeed do sheet cakes and dummies for the decorated cake, and friend pays for every bit of it, plus enough money that a person would reasonably make if they were at a job somewhere for the same amount of time. I'm using really simple language here because I don't believe you have the first clue about charging at all, and I'm giving you the simplest explanation as possible. But I would not sell one more cake until you can NOT have to ask a question like this. At least to the public. Give them away all you want to friends, but leave the general public to established decorators who can get a chance to make some appropriate money.
