Affiliation with nopcommerce

I have a e com store regarding hire laptops https://hirelaptops.com.au/macbook-pro-rental . we provide laptops on rent. Can i merge my website with nopcommerce. If yes what will be the procedure please guide me

Your site is not an "eCommerce store".  It's just a "website" (used to promote services and products).
It would not be a "merge", but rather a complete conversion. (Or more accurately, set up a nopCommerce site, and then style it using themes, css, etc. to have your look.)
