Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited. In general, you cannot sell alcohol, weapons, service contracts, animals or event tickets. Also, while not always prohibited, you may find restrictions on how you can sell items in some categories, such as art, gift cards and coupons. eBay, Craigslist and Amazon publish these guidelines on their websites.
If you have a background in marketing and a passion for a particular niche, then organizing a virtual event may be just up your street. A virtual event could span across a day or longer. Individual live sessions would be run by experts in the field. And conference features would include live question and answer sessions, forums, and plenty of free giveaways. Visitors to the virtual event would pay to attend, so the more effective your promotion of the event the more money you would make.
