Do you want to create an updated version of this site and offer it to the developers? Or do you want to create a copy of this site and own it with all the rights? If you mean the second option, how will you handle copyright? Although I agree that the current site design needs tweaking, of course. If you still can't find the right people on the team to create a new site, you can always go to this company https://prosvit.design/manufacturing-website-design/. This company at the link always has experienced experts who are well versed in creating websites using the WordPress builder. I hope I've helped you. If not, please write me in private messages.
