:broccoli: :broccoli: Hello Everyone!

I'm sorry if this question has been answered some where else but any help and advice is much appreciated.
I am new to all this and I want to start my own website, I think I've covered alot of the basics like finding a host and working out my design and stuff. Does anyone have an idea of how much content you should have before you open your site?
I'm going for quite a niche market I guess as it all going to be 3D comics and animation, a bit like gay3dworld.com and Joe Phillips work I guess.
I have already been producing bits for other people and I thought it was time to cut out the middle men I guess
If any of you have experience in this area any advice would always be appreciated.
Thank you!
