I have been developing games for 15+ years, and have a decent amount of experience with Godot as well. I could build your game in little time. Even the first prototype shouldn't take much more than a week. a couple months is a bit more than necessary given the requirements.
I'd be interested in working on this project for a modest fee, breaking the project up into smaller milestones to set up a better pay as I work system. If you'd be interested in hiring me, contact me via Discord: TheChayed
