[Job Offer] Alternate showing combination / Variants

Im looking for a way to display variants of the same product in this case wood in different lenghts

 

See postet screenshot for info.

The marked area in black is the same product but with different lengths.

 

Can anyone make a module that will make me able to have it show like this in product page.

 

Let me know what it'll cost me

 

Thanks in advance
