It takes less than you think to get into the game, this is all you need to get started:
Striping - For a little over a thousand dollars, you can buy a line striper that puts down crisp, clean lines. These entry level stripers are light weight and perfect for smaller lots.
Hot Rubberized Crack Filling - Stationary 10 gal. melters can be purchased for around $600 and could be used with a pour pot ($100), as a low cost way to offer hot crack filling. MA-10 Melters are the most popular melters and go for under $1,000. Cracks over 1/4" should be filled before sealing; offer crack filling and you just increased your potential profit.
Parking Lot Safety Devices - Installing wheel stops, speed bumps or speed humps, is as easy as it gets, especially with the lightweight recycled rubber products that have become popular. All you need for installation is a sledge hammer or hammer drill. There are a lot of concrete wheel stops out there falling apart, offer to replace them with rubber.
Signage - Many businesses aren't up to code with their signage. Depending on where the sign needs to go, you may only need a sledge hammer and a drive cap or a post driver, to get the post in the ground. Attaching the sign is easy.
If you only offer one service, you're leaving money on the table. Customers don't want to hire multiple contractors to handle related services; get in the game and stop sending customers to your competitors.
