Website migration from Wordpress to Webflow

Hi, I have a news content website based on Wordpress CMS and Wordpress theme (with a bit of customisation). I wanted to move the entire website to webflow design (with changes & addition) + change the server from Bluehost to Webflow's Amazon cloud/fastly.

Here's the website: https://rewindguys.com/

Can you tell me how much will it take for the entire migration? I need to know the ballpark figure.
