The price would vary depending on what work you need done.
I am the Technical Artist at a game company and can assist in all areas of the project as a manager AND jump into the grind to do sculpting, modelling, retopo, texture/materials, renders, video editing, sound effects and after effects.
*I spent some time making this list below, I hope it helps.
Here are some approximated prices, as your post stated you were unsure:
Sculpting a Character (per Character) $125
Retopo, Texture/Material, Rigging (per Character) $125
Environment Models w/texture/material $100 (based on filling a UV map)
Animation $1200 (per episode)
Voice Recordings REALLY depend on who you hire. (We have access to fluent natives of many countries) $25-$1000 (per episode)
Sound Effects $200-$1000 (per Episode)
Music (per 60-90sec.) $100-300
I've created several Milestones to generalize the different stages I can help oversee and contribute to. Some of the Milestones such as the character sculpting, is if I do it myself. Other Milestones such as the Environment blocking, detailing, and storyboard I assume would be with a team. Feel free to open a chat with me as I cannot open one with you.
I would be more than happy to assist with your project as part of a team. I can make myself available anytime day or night with some notice.
Let create something amazing!
