Yes, I can help you. However, I should mention that I am not a plant broker. Plant brokers simply find you a plant, tack on 8% to 10% to the price, then sell you the thing. After that, they contact companies like mine to help you get it running. Here at C.M. Consulting, we operate a little bit differently.
