If you live in a country that attracts thousands of visitors / tourists, then you can look towards starting your online hotel booking business. All you need to do is to enter into partnership with hotels around you so that when people book their hotels from your website, they will pay you commission based on the agreement you have with the management of the hotel.
Never Assume — One huge mistake that your sales team could be making is assuming an ignorant buyer. Internet leads tend to be VERY educated customers, and they will know if you are blowing smoke. Assuming that your customer is uneducated is a huge mistake for any sales person. A good way to not fall into this trap is by asking your customer the research they have already done. Simply saying “What research have you already done on (The Product), because I would hate to waste your time by telling you things you already know” can save you time, and help you close the sale more.
Multi-vendor marketplaces, like ThemeForest, can be very successful. Chose a niche and create a vendor website for it. Your marketplace could be anything, from a platform for local artists to sell their work on, to an online digital product store. Once set up, invite people in that industry to sell their products on your site. You take a percentage of their profits when items sell.
