A "cold cut" saw would work - it turns a bit slower than the average

You have a solution with your friend doing it. But do not knock using a table saw with carbide tipped teeth for cutting aluminium until you have tried it. It is noisy, but quick. And the finish is not bad. Try searching on " cutting aluminium table saw ". You will get a couple of pages of links to that topic.
