I'm in the process (with a fellow friend ) of putting together a flight sim website. The idea of the flight sim website is to allow people to share liveries. At the moment it will be FSX only but in time FS9 will be added.
Also if anyone has any requests on liveries please let us know as we will design and put them together for all to use. If you're interested in either added your own livery or request please email us @ firstname.lastname@example.org thanks.
ps i will update when website ready.
Last time I looked the market was already saturated regarding liveries/textures. You'll be up against some stiff competition.
