Requirements for a virtual assistant?

i have a 3 month old son and need to start working, but would like to stay home to raise my son. I am very skilled with computer technology, the internet, microsoft word, excel, powerpoint, ect. and am looking to become a part time virtual assistant. I would like to start small helping with simple tasks. What are the requirements to become a virtual assistant? How do I get started? and what is the average income?

According to http://en.wikipedia.org/wiki/Virtual_***...
"A Virtual Assistant (or simply VA), is an independent contractor providing administrative, technical, or sometimes creative assistance to clients--usually to other independent entrepreneurs and solo and small business practices, such as that of a lawyer or realtor. Virtual assistants work from their own office (hence "virtual"), thus making it a fairly popular (and growing) profession"
You can start as Graphic Design / DTP, Illustration / Cartoonist, Copy editor/Proofreader,

although Virtual Assistance jobs have been out for a while, i don't think there is a solid plan of information as to the amount of money that could be made

But to get started you will need to market yourself to local businesses. Schedule appt with small business owners and let them know what services you offer

The basic requirements is pretty much what you already listed.....computers, software applications, fax capability, phone access, internet access etc.
