Logo for GeoCheckpointing - outdoor activity for GPS users

This is what GEOCHECKPOINTING.COM was looking for in their logo design

I need a logo for GeoCheckpointing, new outdoor activity. Please check out http://www.geocheckpointing.com to get better idea.

Colors:
In the top-right corner of the website you can see a picture from online logo creator. It is presented just to show you where I plan to use the logo. So use colors which will harmonize with the website design. Logo will be also used on printed materials.

Logo appearance:
Something like the example at http://www.geocheckpointing.com (but more professional, of course :) ) - there should be text GEOCHECKPOINTING.COM and graphics containing nature, optionally also a figure using a GPS device. Please keep in mind that the logo is not only for the website, but it will be also used on printed materials. Read more
