I'm kind of feeling just a pure lettermark for you. It's customized strictly to your company, so your company IS the logo. This way you aren't sharing any separate generic elements with other companies in the same field.
I like the way this one looks. It's got the mechanical element, along with a sense of motion from right to left. It's perfect.
Hey, after pondering over #47 and #51 , specifically #51 I've noticed a way to improve on the middle letter. This change would really make this mark solid and I would like to present it to you. Only the 1st ranked designer can submit changes during judging so you'd have to rank me there temporarily for me to upload it.
I really wish I would of seen this before the contest ended. It's subtle, but sweet as well.
Thanks for considering my designs and best wishes with your new logo.
Just think of it like this... in #51 the "P" extends all the way down like a normal letter, which makes the gear effect only on the bottom of the "A"... it only shows 3 teeth.
I've modified it and it looks nice. It looks great in other colors as well, even just one. One color is the mark of a great logo.
