Open Cart Shop Customisation

i am looking for someone to work on my website.

In the body of the site (currently where the animation is) we would like to add a 'Mattress Configuration' tool with 3 columns:

Column 1 – Size – Single/Double/King
Column 2 – Thickness – 6"/8"/10"
Column 3 – Covering – Quilted/Unquilted

Once you have selected the your options it presents you with the most suitable produce. Ideally in a box below the columns.

This is to basically guide customers through the mattress options. The columns apply for 'Memory Foam Mattresses' only.

Our current developer has made a start by the columns at the very bottom of the shop 'Categories'

I would also like the design of the columns to be larger and a bit more pleasing to the eye.

If you have any questions, please let me know! I hope it makes sense and further explanation can of course be provided.
