If you want to get started with making money online, then you might consider a service such as pclink.co.uk which can sell you a ready-to-go internet business. For example, you can buy an out-of-the-box computer shop or internet dating site. The site would be mostly automated, so your main job would simply be to market and promote it.
I personally like to build my internet businesses from the ground up, but I could see how it would be much easier for a person without as much technical knowledge to start with an out-of-the-box solution.
Of course, starting any business is a risk. Do not spend more money than you can afford on a new business, and do not count on any income from the business because it may not work out. Try to avoid making business-related decisions on a whim. Think long and hard about any business decisions or other major financial decisions.
