I guess they have no clue yet
no logo, no website, no skins - demo racers :P
The best way to get an own design for your team is (imo) to make one yourself, even if you have never used any of the common graphics programs.
If other people do all the work for you, you will never be really happy with it, depending on how far communication can go. You can't explain someone else exactly how you want the car to look, so it will never be perfect.
And if it's required to change the skins (when some new members join for example, if you are using personalized skins, which I can not recommend), you will be running for this guy until the end of your life.
Trust me, being independent in this context it a true benefit.
And when your first skins look like carp... well, you will learn and get better, the more skins you make
