If you've worked with surfboards you already have enough experience that I say dive in and don't be afraid. No mater how you slice it building an airplane is a time investment. Of course it depends if you want a jeep/tractor or a luxury show piece with leather interior when you are done.
You'll no doubt want to build a few surfboards with epoxy and glass to get the feel for it.
Don't let the idea of molds scare you away. Rutan's famous for 'mold less construction'. Which is basically making a surfboard... ie wrapping a piece of foam in glass/carbon and wetting it with epoxy, using a light weight filler (epoxy and hollow glass micro spheres). This is how the wings are made (sort of). The fuselage is sandwich construction, and is a bit different than boat hull construction.
The only major difference I suppose is that surfboards typically use polyester resin and aircraft epoxy and of course you have to be more careful in how you do the layup to get an airworthy structure when you are done.
As Dan mentioned Richard (who I also know) has the molds for the Q2. I e-mailed him and confirmed he still has them. So there is hope to have a new 'kit' made.
If not the plans built Q2 that was mentioned a few posts ago is built with what I call the barrel method. Basically make a few forming sections using the plan templates to hold the fuselage and then using narrow strips of foam to contour the shape much like boat building. See the post here

This method is very similar to what I was looking to do. Except I have 3D models now and can generate drawings of them. So I was going to make a bit easier to work with drawings and have them laser cut to fit together. Sort of like making a wooden barrel.
One of the reasons I didn't get further with my effort was that I wanted to change a few things on the design. That quickly turned into a list of things I wanted different and eventually made a different aircraft altogether.... but I have some CAD files...
Let me know if this helps at all.
