I can create shots with the phone outline or without as you choose.
I can make different background colors (Even images) and any font of your liking.
Just send me your 1 screenshot for phone and 1 for ipad and you will get a ready to use set to upload to itunes store.
Each Gig is for 3 images for all sizes needed for the itunes store (3.5,4,184.108.40.206 and ipad). Extra gig if you have more than 3 images.
I turnaround work in less than 12 hours (Less than 6 if its in US day time).
