Affiliate marketing presents a very low friction entry into selling products online. While you do need some type of audience to sell these products or services to, you could make a significant amount of money from home while doing it. Some products or services have very high earnings per click. That means, if you play your cards right, you could easily make a large profit on conversions by driving traffic to specific offers as long as you target the right interests.
You can potentially make even more money by offering to handle snow removal in the winter. Shoveling snow is often a homeowner's least favorite job, and there are many homeowners who simply cannot handle their own shoveling because of physical limitations. Typically, snow removal companies charge a flat fee for the winter, no matter how many times it snows. You can offer to remove snow a la carte, or you can copy the standard procedure and charge a flat rate. If you already own a snowblower (or can invest in one), this can help you speed up the snow removal process and allow you to take care of multiple neighbors each time it snows. (A snowblower will also save your back muscles!)
