Roblox Game designer and creator

I need someone to create a ROBLOX Game.

Multi-Player
3D
Online
To be available on all major formats

Set in a desert environment this game is a obstacle / search adventure game where avatars have to make their way to eight separate desert locations where they will search for three to four tokens / keys and clues that allows them to proceed onwards.

After collecting all the clues and having worked their way through all eight locations they will have a portal open taking them to the next level.

There are five (5) levels....

Can you price the above for this?

Thank you,

NEIL WATSON
