I am looking for some advice on pricing containers that I plan on planting for clients. I am planning on planting containers either at their homes with their own containers or selling them containers that I have. I will be advertising my container/windowbox designing and planting business to prospective clients and I just do not know the best way to go about pricing my services. Do I charge them for materials (soil,container and plants) and then charge a flat fee for each container? I can get the plants etc. at cost so I will be able to mark them up to retail, but I am not sure how to charge for my services. Any advice would be greatly appreciated. I do garden maintenance and charge an hourly rate, so pricing is a little new to me.
