Teen boy voice for audio book

I'm looking for a teen boy voice that can also do other voices. The book about 30,000 words .Most of the book is a 15 year old boy, Ryan, reading his journal. I don't want someone to try and do voices of the other characters when they speak - but something to denote they're in another voice. The character of Ryan should be someone re-telling the story of his encounter with a ghost - he's secretive, a little scared, and has a dark sense of humor.

We are hoping to have this done by the end of January, 2020.

Here's a sample with mostly just Ryan to try:

There was a moment not long ago when I thought: This is it. I’m dead.

I think about that night all the time and I feel the same fear I felt then. It happened two weeks ago, but fourteen days and nights of remembering have left me more afraid and uncertain than ever. Which I guess means it isn’t over yet. Something tells me it may never truly be over.

Last night was the first time I slept in my own room since everything happened. I’d gotten in the habit of waking in the hospital to the sound of a nurse’s shuffling feet, the dry chalk-dust smell of her skin, and the soft shaking of my shoulder.

The doctor will visit you in a moment. He’ll want you awake. Can you sit up for me, Ryan?

There was no nurse or doctor or chalky smell this morning, only the early train crawling through town to wake me at half past five. But in my waking mind, it wasn’t a train I heard. It was something more menacing, trying to sneak past in the early dawn, glancing down the dead-end streets, hunting.

And a sample with someone else talking to try:

I remember the day we walked into the library, the little bell tinkling at our entry.

The room smelled musty, and I wasn’t certain if it came from the old books or from the woman who guarded them. Sarah peppered Gladys with questions as I ran my fingers a long the spines of the most boring books I’d ever seen, until at last Miss Morgan put her hand up and spoke.

“This town wasn’t called Skeleton Creek until 1959.”

She reached beneath her desk, which had sat decaying in the same spot for a hundred years, and pulled out a wooden milk crate. Inside were newspapers, torn and yellowed.

“You’re not the first to ask about the past, so I’ll advise you like I’ve done the rest.”

She glanced past the dark curtains to the street outside and shoved the box across the desk, leaving a streak where dust had been lifted. She had a peculiar, superstitious look on her face.

“Read them if you want, but let it go after that. Beyond these you’ll only stir up trouble.”

Gladys took a white cloth from her pocket and removed her wire-rimmed glasses, wiping them with wrinkled hands and casting shadows across the peeling wallpaper behind her.

“I’ll make a note you’ve checked those out. Have them back on Monday or it’s a dollar a day.”
