No, you do not.
You may use whoever you wish to as your web host. While we have some of the cheapest web hosting prices, we understand sometimes you want to have full administrative rights to your website such as FTP access or cPanel access.
If you wish to host your site elsewhere, after we develop the site just let us know. We can send you a .ZIP file of all of your website files as well as a .SQL file of your sites database.
We do not support any third party hosting what-so-ever. So if you do not host your website with us, we do not support your website in any way once you move it from our servers.
