First of all. Why do you want a website? Most of you would answer to affordably market your service to a large base of potential base. Well if that is the answer then why do so many websites get built (often even looking quite presentable) such that they cant get found. If you buy a car for travelling about you would be quite unhappy if it turned out that it was an amazing car with one little hitch it had no wheels. So why do people not get upset with the web designers who produce so many of these web site without wheels.
Secondly building a website is an ongoing process. Just like your business it needs to be promoted. Without the promotion your site will fail just as would your business. I have used the product site-build-it to build this site. It has been by far the easiest and most effective method that I have come across to create a website. What I really like is that you do not need to get involved with the technology you just fill out the forms and your site gets built and promoted for you. Even complicated things like setting up ezines is catered for at no extra cost. After just a few hours a day for a few weeks you will already have an up and running website that will bring in the increased enquiries you are looking for.
If you have any questions about any of this then drop me a mail or give me a ring 036/3523143 and I will see if I can help you. I am not an internet expert or an internet provider rather a tiny guest house owner in the foothills of the Drakensberg. All I can give you is a wealth of information on how to go about promoting your tourism service by building a website yourself affordably.
