Going along with the "Lab" term in the title, I think a chemistry beaker like the attached file. But I am not married to this idea and would be open to other suggestions. Another idea I have is something incorporating an arrow, which goes along with the OnTarget part of the name. I have uploaded an image of an arrow since I'm referring to an actual arrow from a bow and arrow, and not just a pointing arrow. I am DEFINITELY open to seeing other ideas outside of just the beaker and arrow ideas though.
I want the logo and website to have a combination of both professional (the way most consulting and law firm designs usually are), and tangible/concrete/solid, which I think is more unique in this area. By tangible/concrete I mean the feeling that the logo/website colors are more solid, such as wood/metal textures.
I would like the logo to be a little more "fun" than the typical 100% professional look of most consulting logos, but not too far since it is still a type of consulting.
For the winning designer, I will likely want to work with them on a 1-to-1 project for the business card design.
