This is a hard question to answer because there are many different tasks and jobs you can apply to work as a Virtual Assistant and Virtual Professional. At Virtual Latinos you can get paid anywhere between $5 to $20 per hour, for part-time or full-time positions. This will depend on the job you are hired for and how much the client is willing/capable of paying.
The rate you start with does not necessarily mean that it is the rate you will have throughout your entire work relationship. Some clients give out bonuses or commissions for great performance and others even promote their VAs or give them a salary raise. It varies by case.
