Fog Light Hole Help For 95'

I just got my courtesy fog light kit and i'm about to install it myself. Only problem is that i have a 95 gle, and the place that the fog light goes is blocked by a plastic surface that i have to cut out. somebody suggested that i use a heat gun to sorta melt it, and it would cut like a hot knife through a butter. Although that sounds good, that means i have to buy that Expensive heat gun... I tried a exacto knife, but that was too thin and was about to break. I need suggestions on tools!! OR, does bodyshops cut it professionally for a cheap price?? If they do, hopefully around $10-20ish?? I need help!!! If people did install it them selves for the 95-96 models, please reply!

use dremel, it work well, slowly but well :)
