I'm looking to apply at a few equipment rental houses, but

I've been job hunting for a month since I caught wind I was going to be terminated and not having been able to get hired yet has been a blow to my confidence.
I'd like not to fuck this up too.

I've done my research, I've got a resume written up that I feel fits these places, but I'd like to hear some advice about this from other people first.

Final bump.

Definitely an in person visit would be best. Phone calls a few days after to follow up.

It puts a face to a name and it will give off the impression you take care of things personally. Be sure to bring a copy of your resume and talk directly to the manager or whoever is in charge. No one gives a shit about hiring you except that guy.
