Hi Diane,
I don't usually recommend going this route for various reasons, but you might look into:
Office Live,
Weebly,
Yola,
Webs,
WebStarts, or
Google Sites (just to name a few) to get you going.
These all offer free versions, most with ads and limited capabilities, but could be a start to get you out there on the web. Then when you are able dollar-wise I would most definitely (
strongly suggest) go with a hosting provider for a more professional route (e.g.
BlueHost is what I use for all my sites) with your dedicated URL instead of having to use for example:
www.mysite.officelive.com... (or something similar).
HTH a bit,
