How to become a kitchen fitter?

Hello I'm a qualified bench joiner and have been for around 5 years. I'm looking to move into kitchen fitting but unsure on how exactly I go about this.

I have fitted a friends kitchen so have some experience.

I'm based near Stratford Upon Avon and any advice would be appreciated or if anyone is looking to take on an extra person let me know and I can get a cv sent over.

Many thanks
