The service your offering is great however the fundamentals of it are flawed. Your asking people to pay you to recycle items then keeping and selling the byproducts ie nickel, lithium, ect. profiting twice over and not offering anything to your customers. In the long run this will be your companies downfall and its a shame because if you were to cover the cost of containers and shipping as well as offer monetary incentive for your customers, you would gain more overall business and still profit from the byproducts you keep minus this suggested overhead. Best of luck...
