Research selling prices of items similar to yours. Look up completed sales or current listings of items similar to yours. Find the high- and low-end prices, and price your object around the median price level. If you want your item to sell quickly, price it at the low end. The condition of the item also affects the price. Items in poorer condition should be priced at the lower end. Also, consider how many listings there already are of items similar to yours. If many similar items will be competing with yours, you may have to set the price lower to get the sale.
If you have an eye for design and some experience of creating websites, then you could offer your services as a freelance web designer. You will need to create your own stylish website, and have a few other projects that you can show potential clients to demonstrate your skills. You will also need to initially spend time emailing businesses to promote your services and find work.
Start by taking other courses you’re interested in: Not only is this important competitor and opportunity analysis, but it also gives you an idea of how a course could or should look and feel. What’s the pacing like? Is it via email, video, in-person chats? Once you understand how you want your course to look, it’s time to decide what it should include. Those same courses are a great starting place. How can you make your course better or more interesting? Do you have experience others don’t?
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Developing and monetizing microsites can also garner a serious amount of sales. These sites are advertised within a partner site or on the sponsored listings of a search engine. They are distinct and separate from the organization’s main site. By offering more focused, relevant content to a specific audience, microsites lead to increased conversions due to their simple and straightforward call to action.
Research individual companies in your desired niche: If possible, it’s always better to become an affiliate directly with a company (if they have an internal affiliate program), as no one else will be dipping into your commission rate. This is the preferred route for most of the prominent affiliate marketers, including Pat Flynn. Unfortunately, it’s also the most work, as you’ll have to do the research yourself to see who offers programs (they’re usually listed in the website footer).
