Digital preflight script

Need scripting created for online preflight program, similar to those already inplace for Press Ads. (similar to [login to view URL], [login to view URL] or [login to view URL]) Preflight checks need to cater for ad dimensions, file size, etc. Ideally, an online program would be required to allow users to upload ads, perform preflight and send to publishers. Secure access would also be required for users. Database will be needed to carry ad specs from various publishers.
