how i can earn money by website designing?????

There are people earning fairly well designing websites and maintaining them. Often they are hired by someone to create a website for them and of course input data and make good designs for publishing. This requires knowledge on website designing of course and not having any knowledge in such would obviously bring you nowhere. I have a friend who does web designing, of course he took a course on how to make such design. He is doing quite well since he has costumers calling him to make a website as well as maintain the website.

I have been designing web sites since 2001 and it's a great way to make money but those you plan to build web sites for will not want someone that doesn't know what they are doing so I would suggest you really do some studying or you will have some angry clients.
