Hi,

I think once you have the skills you will then probably need also an own website,
or let's say a page at Behance (Adobe Gallery) to show your works to clients and
do not forget the competition is very tough, because sides like fivver.com let
allow people from all over the world to offer their skills for very very low, which
makes competition even harder, because there are people who uses free Blender,
for example, which you have to compete against. Well, just saying. But do not get
frustrated by that and make your dreams come true!

Regarding at what age I started, it was in my 20's and I started with an Atari ST 520+
with 3D software, which name I forgot. Before that I did 3D looking computer graphics
on my Atari 800XL with a graphics tablet and that was when the Atari 800XL came out.

Regards
Stefan
