Wordpress Plugin - Squeeze Page/Sales Funnel

I'm looking to hire a professional WordPress plugin developer with strong HTML and PHP skills to develop a squeeze page/sales funnel plugin. Following is a brief description of the plugin functionality. I will provide more detailed descriptions and screenshots to the shortlisted candidates. 1)The plugin should be capable of producing unlimited mobile responsive squeeze pages and download pages. The squeeze pages and download pages should be customizable (based of various templates), be user friendly and deliver a unique page when the page settings are altered. The page setting should allow for elements such as headlines, sub-headlines, video/images, bullets & benefit statements etc to be customized. 2)Easy integration with major auto-responders like Aweber, GetResponse, Mailchimp, Infusionsoft, Imnicamail, GVO, SendReach etc. 3)Some simple built in analytics/statistics for tracking. 4)Built in graphics library and background images (files for this will be included). 5)Ability to add logos and headers both text and images. 6)Allow social sharing of pages on popular sharing sites like Facebook, LinkedIn, Pinterest etc 7)Redirect scripts built in to direct exit traffic and also opt-in traffic and ability to add further scripts The description above is only an overview and should give you an idea of the scope of this project. As mentioned, I will share the very detailed specifications of the plugin and screenshots to go along if you are shortlisted for the project. Please note that I expect the complete code for this plugin to be 100% original. I will provide you with sample files, so you can get an idea of the functionality that I'm after, but the code you write needs to be original. The payment for this development will be done in 3 stages. One-third after the alpha version is completed. This will include the design of the plugin's dashboard, the page templates and page settings functionality. The second payment will be made when the beta version is delivered, i.e. the remaining functionality (analytics, social sharing, redirect scripts etc) has been programmed. The last payment will be made once the plugin passes the Quality Assurance (QA) stage, i.e. all the bugs are fixed. NO ADVANCE WILL BE PAID, so only bid if you agree with this. Please only bid on this project if you're confident that you possess the technical know-how, have good communication skills and are happy to get onto Skype to discuss the details of this project, can deliver on time and the 3 part payments suits you. When you bid, please include your WordPress plugin development experience. If you have any questions, please feel free to ask. Please use the phrase 'plugin development' in your response. Your bid without this will be ignored.
