Who is author / creator of theme

Since I have not received any replies to my topic, I’d like to find the author / creator of my theme to pose the question to. I believe the creator is “Di” who seems to have created many sites. Can anyone tell me who “Di” is?
Thanks
Jeremy

Here is my page: EnvisaSearch.

Here is the demo page that I want to duplicate: Demo.

These are both wordpress theme 29257 “Consult” (some file folders however indicate theme1063).

I want to change the stock photo of the 5 people and the words to the right of it which reads “It is difficult but possible.” The lettering is in fact an image as well.

Replacing the images themselves would be easy enough, except that I want to add a rotating image gallery plug-in in its place.
Since I can’t edit this default pre-packaged home page, I would like to create a static page to duplicate it (unless you can tell me how to edit this prepackaged home page).

The problem I’m having with the static page is the recent blog post widget on the right sidebar. As you can see from the demo page, it is underneath the image. When I create a page, the widget moves up to the right of the image because the page acts as a blog post. I want to add the replacement image on the static page so that it extends all the way to the right (just like the demo page) and above the recent posts widget. How do I go about putting the recent blog posts widget below the image (or gallery plug-in as it will be).
