You find other web pages like yours and ask them to exchange links 4 with you. Then when someone is browsing a page similar to yours, hopefully they find you. If you click on it the browser takes you to the new location. The easy answer is yes, but it is still too early in the history of the web to assure success. It's a competitive marketplace like anywhere else.
People are still reluctant to use credit cards, even with secure encrypted transactions.
Toll free 800 numbers have been the most successful means of ordering from web pages, followed by secure transactions with a credit card. People also want to know your business exists in the real world, that you have a real address, that you are accountable. Use a photo of yourself, put in what professional organizations you belong to, testimonials from customers, be clear about your guarantees. The web supports your business, it doesn't dominate it or direct it. So it can't be the only way you market your work.
