You can expect a completed website of your choosing (whether it's a blog, an ecommerce store, or a marketing agency) with AT LEAST 7 pages. The website will look professional, but will be much more elaborate than the $2,500 package - there will be mega-menus in the header, more pages, a 404 page, along with blog posts and archive pages (these will take much more time and effort). The website will be made on WordPress, and the hosting will be of your choosing (depending on your personal budget). The website will be optimized for speed, along with compatibility with mobile and tablet screens.
Specific plugins can be installed if the client wants them.
