Hi. After reviewing your brief, this is what I came up with (#6). I experimented with the positive and negative space in the "H" initial to create a box to represent the packages you deliver. You'll also notice that the orange sides of the package combine to create a forward moving arrow, to represent delivery. The selection of orange also suggests economical pricing.
If you have any questions, comments, or would like to discuss, I look forward to hearing from you.
