Most of the marketing people needs a team and like you said repeating a tried and tested formula works for them and linkbuilding and seo is a repeating tasks. I'm not an expert on this but I have worked to several teams in the past that I work for some where my tasks includes off page SEO and then the rest of the team are off to collect emails and some create articles. I suppose he needs a partner who can do some of these or Tim will need someone with skills to collaborate.
And you miss my point yet again. Please read what Vod said.
Or let me just quote myself again
Why should someone that has already invested his time and money into acquiring these highly sought after skills (according to you), then why should he work for Tim the Youtuber?
What value does Tim bring that such an individual would need Tim and that too without getting paid for the hours?
Why should anyone who is skilled or unskilled collaborate with Tim? Why? That too for free.
You might argue that this is just working for a percentage from future clients but looking at Tim's success rate so far, it is a gamble.
Of course, Tim might improve what he has to offer, he might get famous with his youtube content :

It's just a matter of time till Tim becomes a big name.. and my point is, the people that he is asking to collaborate, might not get anything for their 'hard work' in the meanwhile - which could be a long time.
