Logo for Coupon Website - Coupon WatchDog

We need a logo that will be used for a coupon website that will be launched very soon. We have many competitors in this market so we really would like something fresh, modern (young), clean that will stick out.

Once the logo has been selected, the winner will get have a great chance to also get the "web page design" as contest will be opened shortly after the logo is selected. Ideally would love to have one person do both.

CouponWatchDog.com

We would like a logo on a white background.  The logo should be ideally a watchdog character that while looking cartoonish still doesn't look childish.  It should say somewhere "Coupon WatchDog.com" then a tag line that states "Shopping will never be the same"  I am new to this design world so please ask questions and bear with me.  We would like something modern and slick.  To give you an idea...I love the Apple website colors and design.  I like the clean look. This is the first step before having the actual website designed hopefully here as well.  Also, while I think I like all of the above, feel free to surprise me with something different. I also love light grey, blue's, blacks..I also had a friend make an initial logo which can be seen at couponwatchdog.com but I can't say i like it...doesn't really have what I am lookign for.  Other coupon sites that I have looked at and DEFINITELY DO NOT LIKE are couponcabin.com, couponmom.com, coolsavings.com, boring, bland and cheap looking.  Ours really needs to stand out.

I copied this rating system from another CH (thanks) as I feel it makes total sense and will follow through...

Here is a breakdown of how the logos will be rated -
0 STARS: (and not eliminated). Means I haven't had a chance to look at it yet OR I have yet to receive feedback and therefore cannot give you feedback.
1 STAR: Has a thread of merit to it, that is. Unfortunately the rest, are off. OR the main elements that were specified in the brief were not completed.
2 STARS: Has some merit, but others are off and the overall design has not been executed for what we are looking for.
3 STARS: Good, has really good elements to it. In terms of direction… it seems you are on track.
4 STARS: Very good, … and have serious potential.
5 STARS: Amazing!! , if you are the only designers that has obtained 5 stars… then you are the winner!! If several have, then we have a VERY tough decision to make.

- Apple.com colors...I like light greys/silver with bright colors
- Tagline - Shopping will never be the same (smaller than the logo obviously)
- A logo that is different and people will remember...
- Winning Logo in a high resolution file that can be used for multiple purposes.

- Boring, bland, old looking
- completely childish
