If you use self-hosted method you will have the tension of going through the entire process of web hosting, domain registration, web design, at least some coding, maintenance etc which will eat so much of your time that you will barely have time left to put out content for your audience unless a dedicated expert is helping you. And if money transactions take place it is not recommended to use shared-hosting services from likes of Go Daddy. Shared-hosting services are utterly flimsy when it comes to web security particularly when it comes to protecting costumer info.

Wordpress, business version, will get rid of many of these tensions of web hosting, domain registration and web design. It probably is the friendliest to SEO and has tons of very useful features for a whole range of customizations including for low-budget eCommerce stuffs.
