As soon as you can provide a professional performance, and want to start promoting yourself, you’ll need a website to showcase your magic.
Before I get into the website thing, though, I will stress this: Do not attempt any public performances until you can do the magic without giving secrets be possibly messing up.
Just make sure the tricks you plan to do in public are really well-rehearsed. When an magician – ANY magician – gives a poor performance for the public before they are ready, they run the risk of messing things up for ALL magicians. Please give that some thought.
But you WILL get to a point when you have enough tricks that you can arrange into a set (highly recommend scripting it), you’ll need – among other things a website. It doesn’t need to be fancy.
Here is the result of a single page site (it will be built out as I start getting more experience and gigs) I put together today – Ken Orion magic website.
My wife took a picture of me with an iPhone. Then I just put it into this page using WordPress and the Beaver Builder page builder plugin.
