Hey I can tell you exactly how to do that.
Here's one I made with google sites (it's extremely basic, and we've only just started using it so lots of information has yet to be updated).

I used google sites on my google account, which is completely free. On that system you design it all using an on-screen editor which is very easy to use. They have templates and colour schemes etc, but as you can see from the one I've done, I've adapted it a lot by changing the colours manually, adjusting the layout by getting rid of the side bar and title and search bar, and adding my own background image.
Then, go to 123reg or a similar service and register a URL. You can get a cheap one for about 6 quid for two years. This is the only expense. By this I mean
www.(your band name here).com/.us/co.uk./.org/ etc You don't have to do this because google supplies you with a url, but it's quite long and unwieldy and considering it's so cheap to just buy one you might as well.
After you've done this, you go to 'manage DNS settings' and add 'ghs.google.com' (or something) into one of the boxes there, and then you go to the settings on the google site and add in your URL that you've bought. Within about half an hour it'll be working and up online.
Any questions hit me back, but I'd really recommend google sites, because you can update it so easily. I also designed my teaching site using google sites.

Then you have the whole topic of
SEO to learn about, but basically you need to find out what people in your area search for on google when they're looking for a covers band, and 'optimize' your page so that it's more likely to come up in a search with those keywords. You use google keyword search to find this information.
If you type in
SEO on google, there are tonnes of resources for it.
