When should you outsource SEO?

Hi! I'm back with a question.Gradually, I come to understand that I can't cope with the entire volume of tasks alone. SEO, design, PR, PPC, content, and much more. I am very interested in learning new things and developing. But is it possible to simultaneously engage in business and business promotion without losing the quality each of the directions?I often think about the idea of outsourcing SEO functions. Perhaps part of the functions since my business is related to information. I don't want to lose control of what's happening. Advise at what stage to outsource SEO? How much should I do this?
