Building game interface a online community

Hello, I'm working on a project called Lee Space a virtual 3D Space community. The idea is a working Space environment in 3D, using the Java programming code. But the first real task in creating Lee Space is starting with the Interface viewer software that I want to be browser based. The interface will become the be the central control and the first thing you will see when logging onto Lee Space for the first time. The Interface I want to have functions for controlling Lee Space, which will be explained later. One home function I want is social user groups with multi-player. I'm breaking Lee Space into building steps and the Interface is step one, a $550 project. You should know Java and the game engine we have in mind, 1. jMonkeyEngine 2. Ogre3D 3. panda3D I will share the whole Interface project with those interested. Oh, the Virtual Space environment linked to the Interface is step 2 $550 to $1,000 You must the required time needed to build this and experience in computer programming.
