I Need my site to be revamped with new look and feel

I Need my site to be revamped with new look and feel and a lot more product categories. Please visit the site (https://www.onesociety.shop/home) and study it. I need fresh ideas.
I'd need hosting too, any suggestions would be highly appreciated.

I stumbled upon this site(https://thinkwebindia.com/) and I liked the way this site has used the on screen real estate, i.e., The width of the page. Check their Portfolio section [https://thinkwebindia.com/our-portfolio/], I loved the way ther blog is shown, using the maximum possible width. The way these guys are showcasing their images, I Love it.
I want to display my product image gallery on every page like this [https://thinkwebindia.com/portfolio/saviour-geo-location-enabled-peer-assistance-mobile-app/].  Details on the gallery can be discussed later once the job is finalized.

I'd like something like this to be built but with ecommerce features. I need a payment gateway that works flawlessly in India. The site should be able to accept payment in multiple currencies, viz.,
Indian Rupees, US Dollars, etc. I'll need to be apprised in advance of the charges, if any, from the payment gateway.

Please respond with your quotes, estimated time to build and POA of the build! I'm attaching 3 images that are a demo setup shared to me by a freelancer.
