Can I recommend that you could get a LinkedIn profile, it could potentially help you network with employers and clients alike.
It sounds like you have a wealth of experience and skills in the industry, have you ever considered going freelance? I don't know the industry, but its always worth a suggestiong if your an established professional and have a good portfolio/CV/repuatation.
Are you experienced with e-marketing, ie. online etc?
Lastly, if you havent already, sign up with reed.co.uk - they are the largest recruitment agency/website in the UK (they advertise for other agencies and employers on their website), and a LOT of professional jobs are posted on there. If you tweak it correctly, you can get daily alerts sent to you with details of jobs that may interest you.
Above all, best of luck in progressing you career!
