Simple 3d Camera movement / Animation on Blender

Hi,

This is a one-time project for now, but if it goes well there will be more similar work in the future.
I've purchased this 3D scene: ----------
I need two things done. You don't need to model anything from scratch — all additions should just fit the existing aesthetic of the scene.
Part 1 — Scene modifications
Fireplace area:

Slightly reduce the grass around the fireplace
Expand the dirt/clearing area next to it
Add a cut-down tree trunk in that clearing (the kind people would sit on)
Add a blank open book placed nearby, ideally resting on a second cut-down trunk

Campfire:
Replace the existing campfire with a bigger one
Spell out a name using stones on the ground next to the campfire

Part 2 — Animation / rendered shots
My PC isn't capable of rendering these, so I need them produced in 1080p on your end:

A few general shots showcasing the landscape, lighting, and overall atmosphere
A few shots that start with a wide view of the landscape and then slowly transition into a full-screen close-up of the book whilst its turning night
One perfectly looped shot of the book at night, with the firelight reflecting on it

Let me know if anything is unclear or if you have questions before starting.

I need the renders + edited project file: please give me a bid on how much you charge for this and a portfolio with recent projects
