Question about setting up site to ask user to decide to go to residential or commercial

I currently have a website that represents a paving business. Before it goes live, I wanted to create duplicate pages for the commercial division with the same structure, but different images and text.
My plan is to add a page and make it the home page. This new home page would have just 2 buttons asking the user to select the residential or commercial website before being directed to either residential or commercial. They would also be able to move over to the commercial or residential site from any current page by clicking a menu item.

Does anyone have advice on this or an example site? Is there a better way to do this? Would I run into any issues with this plan?

Thanks for your help.
