Business MA = future NQ position?

Should I only apply for firms that offer bespoke business MA courses to enhance my career and ensure an NQ position on qualification?

I am going to start my LPC in September and don’t as yet have a training contract lined-up. But after attending an event recently I’m starting to think it might really be worth doing some sort of business MA before starting my TC. Although I couldn’t afford it, I wondered if people thought it was worth just applying to those firms that offer those bespoke courses i.e. Simmons, SJ Berwin etc? Or would it be silly to limit my options?
