Mechanic Job in Boulder, Colorado

I need a mechanic who can come today or tomorrow to my place and replace the alternator in my 2008 Honda Odyssey (if you can bring a handheld computer to double-check that this is the issue, that would be appreciated). I can't afford a tow AND the repair. This is our only vehicle, and we do have a full-service warranty that should cover the cost of the repair. If not, I do have enough to cover the repair itself, just not the repair and a tow. The issue: The van was jumpstarted twice, had the battery replaced two days ago, and is dead. When I attempt to start it, the engine doesn't make the slightest sound. Hence my assumption that it's the alternator.
