I'll throw this idea out since you're not sure yet. If you're not familiar with Joseph Crowe, he designs and builds wood horns in Canada. He also sells CAD files for his horns to allow diyers to 3D print the horns, or have them CNC cut locally. If money is tight, you could probably get a pair of these 3D printed locally for a few hundred dollars. Another member here recently did this with one of his 1" horns and they turned out good and measured well. Of course, if within your budget he could make you the wood horns...
