Assuming there are 5,000 people living within a circle of 50 kms (31 miles) from where you are. This comes down to an hour drive from where you live, work, or hang around. There should be at least 3,000 passenger vehicles inside such a circle (centred to where you are). Between private and public parking spots (at work, when shopping, at municipal buildings, etc.), there should be 6,000 parking spots at your reach. Assuming you can capture 20% of such a market in three years. That is 400 parking spots a year. Each parking spot needs two parking bloc assemblies as in the Shop of these webpages. Not looking at where these parking spots are (distance from where you live or work) and how they are spread (as in 10 parking spots here, 15 there), the actual work to install 800 parking block assemblies is about 40 hours (one week of work only, in a whole year). You can get all 800 parking block assemblies and have your own inventory (and save on a bulk purchase). You can buy them as needed as well for a better cash flow. If you charge $100 a block plus installation, your income should exceed $100,000 per year, gross. If your profit is 20% of that, you should earn $20,000 net for only one week of work. Certainly, you need to work hard to find clients (owners of parking lots for passenger vehicles). You can also install more than 800 parking block assemblies per year. Moreover, you can install other products of ours (see our Shop on these webpages). This job earns you money, on the side, and more, if you want to make it a full-time job. You will also be contributing in tackling a health and an environmental problem of what to do with scrap tires when they are no longer fit for service because of wear or irreparable damage.
