Hello! Would love to help you on this! Feel free to email me at: bearboystudiosehg@gmail.com or add me on discord as: jonathangava. So we can further discuss the details and give you a good estimate but as always, a fair price.
You can check my portafolio out, I have been using C3 for over 5 years and I have done everything within this game engine so you can trust that I can get anything done:
