I've attached sample design pieces that we're currently using. I love these and would like the slide deck to mimic them. Please use them as a foundation. The "mountain road" picture I attached is the original image that we've been using in the background.
I've also attached "Pricing for Profit" keynote file that I used for my last presentation. I'd like something along those lines, but re-worked and really polished up nicely.
Fonts we've been using are Open Sans and Lobster Two. I really like the different varieties (Light, Bold, Italics, Light Italics, etc) of Open Sans, too, so please use variety there.

Two main colours for backgrounds are #52B965 and #64B7CE
