I get that. As a freelancer in my situation, I have to hand everything over to a separate business, or I have to spend time managing other people, and being their quality control. That needs time away from being creative. Ocean is not a team leader, he's a creative. From experience, creatives are usually hopeless with timetables, delegation and working in a team, generally speaking.
And keep in mind, Ocean has gone for help, and been let down by the results so that he has to do it on his own. The phone is a great example, this current version is what, his 4th attempt? After trying three different people helping? If you can't find help of the quality you need to get the job done to your standard, you either waste more time looking for help after all the bad help, or you learn to do it yourself. Remmber the music issue? Everyone was upset Ocean was taking so long getting the music sorted, but he was trying not to throw bad money after good. His problem is that he is not a manager or team leader, but he also is the only person responsible for the end result.
THe last thing is exclusivity - as a creative, does he spend all the money buying duplicate assets for a second person to speed up renders, who then runs off with Ocean's investment, makes their own AVN with Ocean's customised characters?
I think also, the barn in WIaB and the sports field in SG are two areas that he got help for, and currently he has a graphic designer helping with the menus (both the game menus/gui and the food/drinks menus in the game). So it's not that he doesn't want help, but trust is hard to justify when you've been burnt with bad experiences.
It's a situation where Ocean needs a bunch of things going right for him consistently (getting on schedule, not running a pc into BSOD, etc), then he can spare the attention to seeing if there are people he'll trust.
