video editing software recommendations

hello,

I am new to all this editing digital video and have been tasked with making a mock commericial for work. My question is what software is best to use if i'm going to have a lot of video which I will need to cut down to about 120 seconds. I have access to Premiere would that be my best bet, I do not really know anyone who knows anything about though. Is there something easier?

I appreciate your help and if this is not the right forum for these sorts or questions could someone point me in the right direction.

Thank you so much!
