Could you talk your way onto an MA course with the BSc you already have? One year full time/two years part time for the MA. I was thinking of trying this a while ago. Worth looking at the Open University.
I already have 10 year experience under my belt with published work and gaining a BA will open doors for me.
Just thought i'd add a good luck and look forward to seeing the different results you produce. More than anything, have fun TC
