I think this is very business professional, with an edgy feel to it. The word "quest" really seemed to leap out at me, so I wanted to draw attention to it with the larger "Q". The client requested a serif font, and no sharp edges or points, so I used Palatino Linotype which has more of a rounded square look. To show a progressive/changing atmosphere, the "swish" orbits the "Q" and is reminiscent of sci fi/space which is definitely forward looking and the ultimate frontier. The red against the black is eye catching and defines the company as both daring and powerful, while the solid bold black text symbolizes stability and security. The "Q" with "swish" is used as a visual interest piece on all the items and is screened into the background. It also makes an instantly recognizable icon for the company that can be used on everything from billboards to TV commercials.

I used a butterfly to symbolise both change and movement, i created it with a treeleaf.
Ofcourse colors and placement of symbol can be altered if required.

Used font is Sylfaen.

A simple logo depicting forward motion. There is a slight gradient on the text but that can be easily removed. Font is Perpetua. Comments are appreciated.

Created a logo with an abstaction of wind in it. This refering to the fresh wind or the "wind of change" that Learning Quest, Inc. will cause.
Also the logo "grows" from left to right, which implies growth of knowledge / business.
