blueprint rollover problem

http://jbfunkconstruction.com/index2.htm

Ok i created a blueprint for a construction company website. If you go to that link, you'll see everything works nicely except for "testimonials" in the bottom left corner. The text is too small for the slice. I want to put it in the room attached to it (the one that says "tray celing above") but that room isnt rectangular like the others for me to slice it w/o overlapping others.

Can anyone think of any ideas?
Could Image transparency work somehow? Thanks.
