Future Plan - D&D

I've been thinking about putting together a D&D group once I get settled into my own place with a job. I've been thinking about games I can run for writers. I have some one-shot ideas -- like a bardy.

But another idea occurred to me; I want to start running games full of Homebrew creations. Everything from settings to character races, from classes to archetypes and backgrounds. I want to support the DM community that is out there creating new material for the game.

Does anyone have any suggestions on where I should start?
