Help Needed W/ CFS1 Scenery Designing

I'm new to scenery building. I used cfsTmap to create the island Vella LaVella (or something that looks like it) where VMF-214 was based. But I'm having trouble puting an airfield there. I've tried Airport 2.10 and the airfield won't show up. I tried Runway3 by Chuck Dome and it created an airfield it isn't on the airfield menu. Anybody have idea of how to make this airfield or if they know where I can find scenery of the Solomons?
