You will need access to the Net in order to service your website, and if you don't already have an ISP, you could kill two birds with one stone and try one of these. If you are already online, it is worth checking to see if any webspace that is included in your package can be used for commercial purposes. If not, having an extra, free, ISP is no hardship, especially if it brings a home for your website.

These free website hosts are more suitable for online brochures or for sales sites where you'd rather take payment by phone fax or letter. Their main drawbacks are that to enable them to offer the service free they support it by putting advertising space either on your pages themselves, or on accompanying pop up screens that open when your page opens. If you can live with that, and also the ungainly addresses that result from the way the sites are organised (curable if you register your own domain, of course), they could be the answer for you.
