I need a Roblox developer

I plan to have the aesthetic be an 1800s architecture and very overgrown. It will be a sort of horror game, but its very difficult to explain. i want there to be a spawn point that takes you down a river on one of those tiny rafts with a small lantern, and that will take you to a large mansion looking building. if you stray too far off the path to the building, you are set back immediately at spawn after having your screen slowly blur to white. once you've stepped inside the building, you're trapped. if you step outside, if you are outside for lets say 2 minutes, over the course of the next couple minutes, your screen slowly blurs into white and sets you back at a dorm room. I have a very set and clear vision for this and the lore that goes with it, but its very difficult to explain. there will be ranks with people working at the building such as maids and many hidden secrets throughout the building. im not sure whether I want it to be a manor or whatever.
