Full Roblox Game Development: Complete Game Ready for Launch

I am looking for a developer or team with experience in Roblox Studio to develop a complete game for Roblox. I want to receive a finished, functional, and tested project that is ready for launch—not just a prototype or isolated systems. The work must include all necessary programming, user interfaces, progression systems, data saving, map creation, effects, sound design, animations, monetization, optimization for PC and mobile, bug fixing, and any other systems required for the game to function fully. I also require the original, fully editable Roblox Studio project file, including all scripts and systems used, with no locked components or dependencies tied exclusively to the developer's account. It is important that the project be well-organized and structured to facilitate future updates. I am looking for someone with genuine experience in Roblox/Luau and, preferably, a portfolio or previous games to showcase. In your proposal, please include: Experience with Roblox development; Portfolio or previous projects; Estimated cost for the complete project; Estimated timeline; What is included in the price; How the development process and deliverables would be structured. Specific details regarding the theme, gameplay, progression, map, and mechanics will be explained and defined with the selected professional. The goal is to complete the project with a fully finished game ready for publication on Roblox.
