Choose a niche (e.g., 1960’s Mustangs) and then create a simple site and post related products and services. The easiest way to do this is to contact existing sellers (e.g., car dealers, parts manufacturers/distributors, etc.), negotiate a percentage of each sale consummated to be paid to you as a commission, and utilize their existing content.
The riches are in the niches.
Do one thing, do it better than anyone else, and get paid extraordinarily well for your specific talent.
Test the waters to determine if there’s a market for a particular idea.
Offer a meaningful discount or perk to generate initial interest (in this case, a free report).
Wait until you have an order.
Create the product.
