Harbouring mad idea about building a 100% scale replica Spitfire. Need help to be put off the idea.

Does anyone know how much a pair of front (main) wing spars costs, approximately (as an example)? I imagine that it is so expensive that I will run away screaming and be put off the idea forever.

Problem with the spars is that they are different size annealed round tube,drawn into square tube then fitted inside each other.Then bent and heat treated to full hardness.You have a top and bottom spar,port and starboard and they are joined by a thick aluminium web.

I don't thinks anyone knows how much. No one does such things, that I know of. I could field a guess that it should be roughly half the cost of an airworthy spitfire. The wing is extremely complex, much more so than the fuselage, with virtually no sraight lines in it. Airworthy spitfires well over a million dollars US, is that scary enough?
One option is a composite wing, but even that cost would be expensive. Engineering, moulds, lay up, finishing, would all add up very quickly. Probably cheaper than the original method, but still lots of $$$$$$. I'm going composite for my project, with an aluminum fuselage. Seems the only option availible to me. I like the thought of a wet wing as well. I'm not real excited about two large containers of av gas right in front of me.
Fuel for thought,

Nate
