# 12 I see you like the Collar and TIe; I am not sold on it but you might trie a sharper or fansier font and use the tie as an L in Sales; split the Blue and the Collar with the pictorial.
It should communicate speed professionalism, and hard work at a glance.
# 19 This has a more technology feel and does incorporate the symbol.
The reference to Blue Collar in the company name means hard work, not afraid to get hands dirty. THe communication intent is that we work harder than most other sales companies so the collar and tie are off the mark.
A hard hat, construction tools, concrete, or steel worker would speak to the hard work part. Something technically abstract or word art might communicate technical capability.
mixing fonts could be good; perhaps a symbol incorporating the BCS portion.
