New logo for fast-growing website - design a BUCKBUDDY

We need a new and more fun logo for intrabid.com. Intrabid targets college students and their need to sell off books or anything else on campus for quick cash (see http://www.intrabid.com for more details). While we signed up over a 1,000 people in a short period of time, the logo had very bad reviews and needs to be rebranded!

intrabid.com | Your campus buckbuddy

The new name and logo should be more fun, more easily recognizable, focused on young college students, etc. Right now, the logo is not fun/recognizable enough. We will stick with the name intrabid.com for the moment, but the tagline will change to "Your campus buckbuddy". This underpins more the real value of the site, which even more so than a campus auction is a way for students to get cash (through selling stuff their no longer need or getting exclusive student discounts).

- The new logo should work both on the blue background and the white background (see current logo at http://www.intrabid.com)
- The logo should be colorful, but the colors should work with the blue colors of the website throughout
- It should be related to "Your buckbuddy", i.e. some representation/link to a buckbuddy (who gets money to students).
- It should look fun and easily recognizable, and support 1) the community campus feel we try to establish (a trusted auction platform on campus), and 2) the ability of the platform to get cash to students (and make them richer by selling stuff they no longer need and getting exclusive discounts on new purchases)

Anything goes, as long as the colors fit with the overall layout of the site (see http://www.intrabid.com).
