Ok, we have a couple of things that can be handed out and some things that are best taken care of on your own. Below are the details:

Social media campaigns management for Instagram and LinkedIn - A smart social media guy can do this on your behalf by using tools like Buffer. He/she can schedule everything on Buffer and you can give it a look before it goes live.
- Blog posts writing and idea generation - This can be outsourced with ease. A lot of content creation agencies out there that can write blogs on your behalf. 4 blogs per month will be enough for you I think.
- Networking - Easy stuff. Once you outline what kind of people you want to connect with, anyone can do it. I get this done for LinkedIn.
- Speaking at public events - You got to do this one on your own. Someone can help you with the PPT part but rest of the show is you.
- Produce in-person events - This will also be you.

The first 3 things can be best tackled by a small team after it understands your language nuances, goals, and expertise. First month will be a little time consuming but after that, it will be smooth. My team handles the same for some entrepreneurs and businesses. Below are a couple of case studies:
