make caption float left and visible

Hi.
Is there any way to make the caption info float left and the image float right without overlapping. I have played with the CSS and I can make it float left and image float right but the caption is not visible. My website is http://www.sheppadviser.com.au/subdirectory
The current width of the nivo slider is 619px and I want the total width to be 819px with the caption not overlapping the image. I need the caption to float left and image to float right. Any help would be appreciated.
Please someone help. I have tried everything I can think ok.
Thanks in advance.
David.
