Improve intershoppy to look nice & for better conversions

Hi guys, I have client who owns the website " Intershoppy" , this website runs on woocommerce and flatsome theme. He needs you to optimize the website, it's look and make it appear appealing for visitors and make them to buy. Take a look at the website and offer your proposal (what you can do & how) and also show samples of your work. He likes this theme layout [login to view URL] , let me know if you can do anything similar to that.
