Custom Website Designed

I have a website idea and I would like to know the approximate cost to have it developed. - Website Purpose - The website is a hub for local newspapers and magazines (possibly videos series), that subscribers can purchase on a monthly/yearly subscription plan. Users will have access to their material to read online. - Important Features - - All subscription material (videos excluded) must be protected from download/sharing. The form of restriction can be done in any applicable way (through embedding, or comverting pdf to a "difficult-to-share" format) i.e. some form of protection must be there to prevent sharing (Primary importance) - Credit card processing / Paypal integration (if possible, using paypals adaptive payment api). The idea is at the time of subscription the incoming funds will go directly to the owner of the material and myself according to the pre-agreed split percentage. (Primary Importance). - The ability to create a new product and set the parameters such as (background image, title, subscription price, percentage split of subscription funds). - Product Page - e.g. a subscription will have its own page, with background images for differentiation, and info/summary about the product. Links for subscription - CMS / Admin / User Page / Manage Users / Disable, Reset Passwords etc - Users will be able to subscribe to any number of material on the website. - When new material is uploaded for a subscription, alerts are sent to the users registered email. - Social Media integration (share buttons, automated posts on social media profiles (for promotion and attracting new customers /marketing) - Able to offer free trials / subscribe to free content (downloadable) / Free Subscriptions
