If you are in a business that usually posts out information, or provides information over the phone, or advertises what their business offers, then a Multi page Web site could be a very cost effective method of getting info to your customers.
Sometimes it can provide all the info required, other times it narrows the search down before the customers need to leave home.
Most importantly if you're not on the Internet, you risk not even being considered as a supplier to the increasing number of people who now rely on the Internet for their research.
Costs of creating a web site can obviously vary, however it's not as dear as you may think or as some others may have told you. We work on an average price per screen full (see price list). However this can be less for pure text information, and more for things like Survey forms, tables and complicated graphics.
There is a once only setup cost to create a layout and style to suit your business, this includes the menu area and the home page details that are designed to welcome your visitors.
The setup price also includes submitting your web site to over 2500 search engines.
