Trying to create a smooth surface with non planar curves. Cannot figure it out!

Hello everyone. I have been looking around everywhere to find out an answer to how to make a mesh from these surfaces but can’t seem to find something that would work. I used to use Rhino a lot a few years ago but completely forgot how to do this. I am creating a skateboard and the top needs to flow with the concave and dips. Here is a picture: http://i.imgur.com/3MnbaFF.png

Thanks so much!

Hi Dan- it looks like maybe a simple extrusion of the ‘side view’ curve, trimmed by the ‘top view’ curve, might do it?
