Well, actually you do. There are over 500,000,000 (yes, 500 MILLION) products that you can promote as an affiliate marketer online. This means you don’t have to carry any inventory for any of these products/services. You simply link to companies through your special affiliate links, and exchange and they give you a cut (%) of every sale that you make.
2 - This is not just for beginners on the internet. There are a large amount of marketers that joined to learn more and love it. So the coaxing part you mentioned.... not really there. You can stay a free member but you just don't get the info that premium members get. You seemed to be outraged about that. Well how about you give your services away to anyone that does not want to pay and then charge the ones that think it's worth it. How soon before you are called out and you have no business at all. So that complaint is just non-sense.
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
