Customizing HelloVideo CMS project

We recently bought the latest HelloVideo CMS v1.1.1 [login to view URL] We however, need to have a few customization: 1. Instead of signing up straight away as a paid user, upon subscription, they can choose to get the "free" user or the "paid" account. (I would want more people to signup for an account instead of just paid user) - The signup form would also need it to be customizable - more field and options for future addons. 2. Paypal integration will be required. (I believe there's a plugin to do that) 3. I need show series creation. (Eg. If I were to click in a video in the main page, it will direct me to the video page. Instead, I would like to have a option to create a show series page. Say, when I enter the show called "The PC World", I will be able to get options to watch different episode of the show. Some can be subscriber based only, and some can be free to watch) 4. We need also need pay-per-play feature. Instead of subscribing monthly, they can choose to pay a one-time off fee to watch that film or series. Let me know if anyone is able to help me with that. Would really appreciate. We do not have much budget for this project, but feel free to quote any amount you think is reasonable and we will definitely consider. Cheers! Lincoln
