Starting out with refurbishing is a tall step to climb. It requires lot's of expensive equipment and you will have to go through lot's of failed refurbs before perfecting your process. Considering you don't have easy access to loans, I would encourage you to start small. Start with repairing/replacing broken screens and make some money that way. You'll also learn the inside out of the devices and the business in general. Then you can branch out and start with refurbishing.
