Get the appropriate number of views, have a clean 'good standing' account and decent uploads, and you can either approach a network or wait for them to approach you.
Ah ok. Well just remember to think about if you really need a network partnership at this time. I see so many people that are so worried about becoming a partner that its all they think about. A partner can only really help out channels that are kinda established. If you are a new channel and still growing I think it is better to go solo until you have a decent "fan" base before you move onto the next level. If you jump into a partnership too fast you may be upset about the cut of your profit they will take.not really no , it's just a new quest on becoming a great youtuber
