Copy/ clone products from shopify website

I need something similar to a current shopify website. I know what theme it is already. However, if possible to do without using same theme, that would be better. I need all of the same products imported. Some changes will be made to the homepage to make it different, but all shop pages will be the same. Change font style and size Change button color, style and size Upload All Product Images , Product Titles, Description Change pricing for all if possible, or i will do manually for all Will need to change homepage to look different (can be default theme style)
