Once hired, creating a weekly or fortnightly task list for your VA can help them to get on with their work without having to constantly interrupt you. You can also help them out by putting together templates and instruction documents for them to refer to. Store your communications and documents in the cloud so that they are easily accessible. A VA is not a trainee. They need to be efficient, skillful and able to quickly respond to your requests, so make sure you set up a trial period to ensure they are capable of meeting your requirements.
