I will have to disagree with Amanda because I started my business subcontracting from day 1 and I am doing great. You can make six figures subcontracting without a doubt however just offering admin services is not enough. You need to offer many services and find the right nich market.
I do not have any VA's that currently work full time for me because I have many VA's that work for me. Some make 20 to 40 hours per month and some are between 5 adn 20 hours per month. Depends on the VA, the service and how long they have been working with me. I do plan on adding a full time assistant at some point in 2011. I need to break away and find the time to train and hire someone. The work is there just need to find the time.
