There is allot of great advice here
One thing that has not been mentioned you may want to keep in mind:
Do not fall for get rich in porn schemes...like start your own adult site and watch the money roll in, commonly known as turnkey website.
Not all turn keys are bad, but you have to know what you are doing. Like they say, if it sounds too good to be true, it probably is.
Oh, be sure to do your research if you are going to give money for any work you may hire out!
Gook luck to you!
