I AM LOOKING FOR ROYALTY FREE IMAGES FOR IPHONE/IPAD/IMAC/LAPTOP MOCKUP SCREENS

I AM SEEKING SOMEONE WHO CAN PROVIDE ME WITH A GOOD SELECTION MAYBE 100+ ROYALTY FREE IMAGES FOR USE AS MOCKUP SCREENS FOR OUR WEB DEVELOPMENT. PLEASE SEE ATTACHED - YOU WILL GET A BETTER IDEA BY LOOKING AT THE WEBSITE PLACEIT.NET THESE IMAGES MUST BE ROYALTY FREE AND HAVE RESELL RIGHTS. HAPPY FOR YOU TO CREATE THESE FOR ME BUT NEED TO HAVE SUITABLE IMAGE SIZES IN PLACE OF SCREEN HOPE THIS MAKES SENSE - THESE WILL BE USED FOR MOCKING UP OUR DESIGNS FOR CLIENTS I NEED AS MANY AS POSSIBLE FOR TABLETS/IPHONE/IMAC/LAPTOP/MONITORS ETC ETC
