Can you specify which design elements of the current blogger theme would stay in the WordPress theme ? Also have you got any design references on which the new theme will be built upon (not mimic'd, just for an idea)

no design reference - else I would have bought a template somewhere and used it... Surprise me.

you need a full working theme or some templates?

I have only just found this brief - am interested. Fairly new to design crowd. Adept at Wordpress design. Should you be considering extending your time frame, will happily have a crack at it. But please don't extend on my account alone! Cheers.
