I don't know what to tell you, I am not any good at modeling but I am awesome when it comes to hammer editor, and I think your best bet would be just to build your level in Hammer editor (Its intention) or make that blender level into a prop then put it in, all you have to do is make a hallow box around the level with the nodraw or skybox texture so hammer will know where the level is for compiling right, although, i don't how you would texture it in hammer, you could export all the textures you wan't to use from the source game with GCFScape for use in Blender.
