Not only will you be providing a valuable service for site visitors, but you will also be establishing your own potentially successful business. The business concept is very straightforward. Start by designing a website that features information about various advertising mediums including rates, contact information and any special promotions or discounts in terms of advertising rates. Business owners who visit the site simply locate the type of advertising that suits their marketing program and budgets. Income is earned by charging the advertising companies a fee to be listed on the site, as well as by selling advertising space featured on the site.
