Welcome to Air-Child, Hans-Dieter!
I hope you're not leaving us so soon, just for a missing repaint, before you had a look at what Air-Child offers apart from that
Let me explain some things: Company repaints are not mandatory to fly for the VA. They are more like an 'extra' to increase the immersion of flying for a virtual company. However, I understand that liveries are more important for some people, and less for others.
Now, as new members always have (at least) one wish for free, we will try to provide the default 737 repaint as soon as possible. But please understand that everyone here contributes to the VA in his spare time, so sometimes (or mostly) things take some time to get finished.
As Andrew already stated, it's more difficult to make a repaint without a proper paint kit (template) for the aircraft. That's why we have more repaints for payware aircraft than for freeware and default models.
In the meanwhile, I suggest you have a look at our flight search, booking & briefing sections, and you'll see that there's more to find here than just liveries. If you are new to flight simulation, don't hesitate to post on the forum whenever you have any questions. We don't have many painters here, but a lot of experienced pilots, willing to help
Grüße aus Stuttgart,
Peter
