Nirvana template- Presentation Page Position

I’ve used the Nirvana template for my company’s website.

Website

Currently, the position of the presentation page is as follows:
1) Slider
2) Text Area 1
3) Columns
4) Text Area 2
5) Text Area 3

I would like to change it to:
1) Slider
2) Text Area 1
3) Text Area 2
4) Columns
5) Text Area 3

I’ll appreciate the help with this.

Thanks.
