I have an aluminum road bike frame that I want to use to build a fixed gear. My problem with this frame is that it has vertical drop out and no derailleur hanger. Fr

You don't necessarily need horizontal drop-outs to make a fixie. You could also get an eccentric hub such as this one. This allows the chain slack to be taken up without using horizontal drop outs. They also have eccentric bottom brackets but I think they require a special frame.
You would have to go to someone that knows how to weld aluminum to weld you on a new dropout. I don't think you want to do that. It would be cheaper to find a frame / entire bike designed to be a single speed in the first place.
