Group Shopping Logo Needed!

Groupy is a new group shopping site, a client of mine requires a brilliant logo for it and has entrusted me to pay $120 to the winning entry.

Groupy

Desired Style:
Clean, effective and professional looking. Not much for specific style - but we're open for creative suggestions.

Accepted File Formats:
Any Vector based format

About the site: The URL for the site will be http://www.groupy.co.uk. The idea is that items are offered in bulk. Visitors to the site join a group and commit to buy an item at a lower price than the retail one. Once the group has been filled the sale is complete and the item ships. The sale is canceled if the group minimum members is not met.

The logo should be simple, yet effective. My client has thought about the concept of an abstract group of people holding hands, but is open for any kind of creative suggestion. Generally the logo should include the word Groupy but we're also open for any creative ideas where the .co.uk is included in it as well.

We require the logo in a vector format.
