I want to purchase specific theme similar to https://www.fwip.com/
Please help me to get similar kind of theme.
It’s custom work
I agree with @ki-themes that this will be custom work. However, you can look through these themes as you were asking for something “similar”.
Even if you saw something, you would still need to make it your own. There is no point in duplicating any website no matter how much that website might look great
