It's not that hard to run 1/0, I had 4 runs along one side of my brothers Trail Blazer. It took a bit of work, but I got it all under the carpet. Either find another shop or do it yourself. Most of the time there are pre-existing channels under the carpet, where the factory wires are, that it'll fit in. A last resort would be to run it underneath your vehicle under the rocker panels, but I try to avoid that at all cost. In the unlikely event you hit/run over something & pinch it you could turn your car into a fire pit.
