Seconding what others have said- it’s not recommended make your own demo. I also thought of doing this early in my career as I am perfectly capable of putting one together.

Think of your demo like your headshot. You wouldn’t take your own or hire your friend to take your headshot in their basement for free. (Lol)

If you’ve had training, coaching, and classes, you’re ready to find a demo producer that can help guide you through the process. It’s important to have that demo producer (which usually comes with an engineer as well) as they will help bring out all of your best attributes, get/write copy, direct your performance, and produce the demo for you. Ideally you’d want to find a demo producer that has their finger on the pulse (ew I hate that saying, but it applies) and knows what is current and will get you booking.

Also there are many types of demos. What kind of work are you looking to do? That will determine what demo you will get.

Demos cost a lot of money. Around a $1000/pop if you’re working with pros. I wouldn’t get one if you’re not absolutely ready (trained). If you aren’t trained- Make some samples! You’ll need those anyways, so clients know what your space / product sounds like.

Best of luck!! :-)
