Logo Needed: Dig For The Doctors Charity Ride To Mines

We are riding motorbikes from Brisbane in Australia to Perth, visiting mine sites along the way and collecting money for the RFDS. We require a logo for our publicity that represents this.

Dig For The Doctors

Tagline:
Proudly Supporting The RFDS

Desired Color Scheme:
Ochre Red, Black, Gold

Desired Style:
Simple, clean and professional.

Accepted File Formats:
Vector please, or Raster if necessary.

We are trying to get across: mining, riding from Brisbane in QLD to Perth in WA via the top end of australia, and if possible motorbikes, but that one is not necessary.
We have in mind a stylised arrow, the shape of the aussie coast from bris round to perth, with the mining crossed pick and shovel in the space below the arrow.(roughly corresponding to middle of australia)
We would like Dig For The Doctors below that, in whatever font looks good.

The above is not set in stone - if you have any other ideas we would love to see them
This logo will go on our website and all our fundraising material we send to GM's and upper management, so we want it to look tidy and professional.
Colours - Ochre Red for Iron Ore, Black for Coal, Gold for...gold, or any other schemes you think would work.
