Help to integrating Highslide into my website

Hello, I am looking for someone to help me refigure the look and functionality of my website. I'm not familiar with the kind of new features I'd like to integrate.
Right now, I'm using Gallery 2, and would like to integrate Lightbox into my gallery. At least, I think what I'm referring to is Lightbox, but it could be something else (not sure). Here is an example from another source of how I'd like my new website to work:

http://mitchellkphotos.com/overview.html

So, the idea is that once someone clicks on my Home page, and then goes into the individual story folders, and then comes to the page of 6 images for the story, I would like the Lightbox function to be integrated into this part of my website (hope this makes sense).

Here is the link to my website:

Once you go into Home and then click on any folder, you will go into a sub-folder (where there will be a page of images). Here, if one were to click on an individual image, the Lightbox show would come in.
At the moment, the way I have it set up, when I click on an image within the sub-folder, I get a new screen with just that image and a small overview of the rest of the images on the right-hand side. I would like to eliminate this part and have something more like what Lightbox provides (i.e. http://mitchellkphotos.com/overview.html)

I hope all this has made sense. If anyone could help me, i.e. let me know how/if this is possible, and also time and costs involved, I would really be grateful, or should I ask directly the paid support from Gallery?

Thanks so much in advance!
