The last type of job in this area is more legit than the rest but most likely won’t produce you any profits.
Many companies who advertise work at home assembly or packing jobs will charge you a fee for a startup kit and then you’ll be instructed to either assemble or specifically package their products.
After assembly you’ll have to send the products in for the company to inspect. The problem is that you’ll never meet the company’s expectations and will instead just be out of the money for the startup kit.
