Hire a smart virtual assistant (VA) capable of performing various activities. This will ensure focusing on your core activities and relatively cheaper cost.

Don't hire freelance VA, always look for companies who provide these services. You will be better of with almost no downtime plus having access to their tool and automation platform.

I collaborated with one, who gave special services like:

1. Flexible hours of work based on need
2. Work as per your desired time zones.
3. No additional Project Management charge.
4. No upfront investment.
5. 100% security i.e. own the copyrights of the work done.
6. Track performance by daily reporting schedule.
7. Rate as low as $8/hour.

Let me know if you need any help.
