How much is a verizon iPhone 5 before my upgrade?

I have a Verizon iPhone 4 with 8 GB. It was a free upgrade when I got it last October. I have a two year contract so my next upgrade is October 2014.It's a bother having only 8 GB of space and I don't want to use iCloud. I would buy basically any model iPhone, I just would appreciate more gigs. Is it expensive to buy an iPhone 4-5 with more gigs? Thanks in advanced! I'm also on a tight budget I have a little over $1, 000 and I'm a student. I need a lot of space for photos, music, and applications.

$1000 is not a tight buget for a phone
