AR RPG location based game prototype

When the game opens, we will see our character, in the backend there will be google maps or a similar map SDK, we will be able to see the items or creatures that we have created in a database like Firebase or similar. For example, the game is opened. We are on a map like Pokemon Go. Depending on our Leng, Long , then if we put an Item or NPC near us in the database, they will start rendering and if we put a chest as an example that we can interact with, its content will be added to my inventory in the database when I press it. Or if I put a creature on tap, a battle session will start and I will be rewarded at the end. Everything will be simple and at the beginner level, I don't expect a complete Pokemon go, I just want the initial and basic version of the system. Characters and animations can be used for free. I can also provide asset support from Mixamo or similar places. Don't make exaggerated offers, I just don't have time, so I have to hand the project over to someone else. If you want to deal seriously I'm going to start the project.
