Design Large Stickers for a car

My girlfriend and I are heading on an overland trip from London to Cape Town, via the Western coast of Africa. We are looking for someone to design some logo-type stickers that we can put on our vehicle.

We have images and ideas of what they should look like, as follows:

1) There should be one main sticker for the bonnet of the car, taking up most of the bonnet. It should be of a large bull elephant silhouetted against a rising sun. Please see similar image attached.

2) There should be a map of part of Europe and Africa, showing all the countries and London and Cape Town clearly. It needs to be visible against the sand colour of the vehicle. The countries can be solid in different colours. This would appear on both front doors of the vehicle and ideally take up the whole door.

3) The word 'Indlovu' needs to very large on the vehicle, preferably near the elephant logo. It should be in black and might be best in bold.

4) Space should be left for a web address underneath the map of Africa, to be advised.

All images should be supplied in .psd format.
Attached is a picture of the vehicle so you can see rough sizes

I have someone who can print the stickers, however if you know someone and can quote on this, it would be handy too.
