After signing up (you get your first-month subscription for free, by the way!) and once your needs and requirements have already been assessed, a dedicated and qualified assistant will be assigned to work with you. There will also be a supervisor that oversees the project and another VA in place to serve as a backup as the need arise. You can communicate to your VA via email or Skype, live chat or phone.
The good thing about the service is that you can link multiple email addresses in your account so other members of your team (works best if you handle a large group of people) can also send tasks.
Average turn around time per task is 8 hours, however, some tasks may need more than that. Thus, the assistant is required to send you a report at the end of the day and keeps you posted on the progress.
