haven't you ever seen an action movie? take a ****'n 9 mil to the son of a *****, with decent aim one shot should do the trick... .45 or just about any other pistol you can get your hands of will probably do the trick as well...

seriously though, I woulda spent the money on a cheap-o grinder before the bolt cutters... I've seen adapters you can put on a regular drill to use it as a grinder to if you have a drill... like someone else said and auto repair shop or something of that nature might help. Or going to the nearest construction site at lunch time with a few bucks might help you find someone who could help...
