Microsoft has revamped its bCentral web site, a collection of services and resources for small businesses. One interesting example is the offer to design and host a web site from scratch for $399. That’s the price for a custom design with a generic but relatively professional look, and five pages of content. Plus the service can scale up for small amounts of online commerce and the like, at equally reasonable prices. It’s one way to get a web presence without a huge financial commitment.
