The timeline is tight. Within 24hours of accepting a bid, I'd like to see a couple 'prototypes.' You should have the ability to capture concepts and convey them visually in a simple and beautiful manner. I prefer the artwork to be designed in Photoshop with a minimum of 600dpi. If you can make the art-work vector-based, that would be preferred. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
