transfering my site from static html to wordpress

i’ve run my dad’s art business website for years using static html in spare moments here and there.

i’d love to transfer it to a back end that he could use to run the site himself – add/remove stock, change prices, pictures etc and i think wordpress and the right plug ins could do it.

the site’s here https://www.merivaleeditions.com/

can anyone advise on how you could use wordpress to display stock in the way the site does at the moment? so far i can’t work out how to assign standard features like artist names, dimensions, prices etc for each page.

thanks in advance
