Hi VA. I am not a consultant, but also wish to merge into consulting, so i am limited on my advise. I work for the NHS. Your understanding of psychology could be important to a marketing firm as marketing is all about understanding the needs, wants and desires of the customer. Different from consulting but also along the same lines is performance coaching. You understand what makes people 'tick', why they do what they do, and how their current behaviour effects their current and future performance. Their is a market out their for coaching top notch CEO's, executives, and entreprenuirs etc. Check it out. It may be just up your ally. If not, maybe getting some business qualifications, like a MBA with a major in marketing or HR will help. Just remember consulting houses do want full time graduates from the top business schools so choose carefully. Hope this helps a little.
