I have been experimenting with Balsamiq Mockup online free software following a recommendation from a friend ours whom also runs a web design company.

I usually sketch blueprints out on paper, which usually takes 5-15 minutes if I have a clear idea in my head for the website layout. The sketches are very rough and I often have to sit with a graphic designer to explain my sketch in further detail.

My first attempt at Balsamiq, it took me 40 minutes to come up with the layout below (which is for a live project). This is not too bad as I was getting familiar with the software and experimented with the layout a bit. Being able to easily move things round is far more effective than using pen and paper (I'd usually start again if I wanted to come up with a new design). Being able to drag and drop common website features onto a design should help both my productivity and the graphic designers understanding. 

I'm keen to try out the full unrestricted desktop software more and intend to get my hands on a desktop version into customer proofing and the design process.
