What courses do you recommend to start freelancing?

Hi all!

I’ve recently graduated from a marketing
management degree, I have some broad marketing experience from internships and jobs over the years and I’m currently working as a Marketing Executive
at a great Welsh brand!

I have a lot of spare time alongside my current job so now is the perfect time to branch out freelance.

I’m thinking of launching my own social media management and paid ads service. Maybe even some basic web design for now.

My question is, what courses would you recommend me taking before I start?

I’m thinking Facebook ads, Google analytics, maybe something data oriented too?

All suggestions are welcomed, I’m uk based if that makes a difference☺️
