Cogarzzz,
Thanks for contributing your ideas. Good start... here are some suggestions:
The font for "DOIT" in #21 is too heavy. Also, the red circle is too thin - needs to be thicker to reinforce the idea of a road sign.
Try some variations where the word DO is stacked on top of the word IT and put the word MARKETING to the right. Inspiration might be the Love statue here:
