I thing to do is to find a supplyer of postage materials, one that meet your requirements and can be supplyed at a price that is right.
second thing to do its to push your identity. You have a logo or icon print it onto stickers or get a personal stap made.
keep it simple
Dont over rap the parcel, this will make it look bad and will mean the clint cant get into it. Try and get self selling packaging materials if posible.
