Many of them will be not be located in your immediate geographic area. Target the big property preservation companies (many of whom are overwhelmed) and offer your services. You will have fill out their vendor pack, which will ask for license and insurance. You will have to provide the zip codes you service. They will contact you with work orders as properties are foreclosed on in your area. They will contact other vendors, too. They often have their own pricing caps. Just b/c you get a work order does not mean you have to take it ... review their pricing caps carefully to make sure you can make a profit from the job. Tons of free info at link below. Good luck!
