To start an own animation company

seems like I've heard of a lot of people who've done things witty and animated and posted them on youTube or similar, people spotted them and told their friends, which turned them into viral hits, and the people with money started buzzing around them. You might try that for starters, see if you can get some exposure.

1. Have the ability to create an animation
2. Have customers who will buy that service
3. Be able to make more than you spend
4. ... then ... Early to bed, early to rise, work like hell and advertise.
