If you are looking for your own wordpress powered sites, you can install it manually to your domain and your prefered hosting. The benefit is, it is yours, and using your own domain. With this, you can customize your wordpress appearance whichever you would (templates are available, and various). I can help you set up a wordpress site, but you have to own your domain and hosting before the installation. This is called wordpress manual installation.
