SW Licensing & registration system design

Please read & understand in its entirety before responding. Do not respond as a robot. We have software products that need registration when a client wishes to buy them. The products may be downloaded from our web site, from a reseller web site or we may e-mail them or send via a physical media. We have 2 types of products for MS Windows - one we have demo mode & another without demo. We have some products downloadable from Windows mobile, Android & Apple app stores also. Which will also need registration. A demo product may have multiple options that may need unlocking from demo mode, depending on what a client wishes to obtain. The non demo products will also need some method of unlocking. We are currently using an old registration system and want to redesign the registration system from ground zero using contemporary features. We need you to define the characteristics for a modern licensing, registration system that has tracking & tracing capabilities & other modern features. The registration may be done via a usb key, via phone call, internet or e-mail or some other mechanisms. There are some online subscription services available also. This project involves you to create a list of features that should be provided in our registration system. Second phase may involve developing it or us using some subscription service you advise that is best suited for us. You may quote a fixed price for phase 1. If quoting an hourly rate, you must provide a limit of hours that will be estimated to be used. We shall assume 5 hours, if you do not specify. We shall assume a delivery in 3 days after award by us. Any delay will be detrimental to us. If you have a solution (must be based on MS Vis Studio), that can be sold to us, you may quote that as well. We shall need full source code with tech support for some reasonable hours. If you suggest a 3rd party subscription service, provide their rates also. Ask any questions, so that you are clear with the scope of work.
