Build Wordpress Plugin and Dashboard

I need someone to create a wordpress plugin and administrator dashboard based on the following spec: 1. Clients will install the plugin on wordpress. It will be called "Kontent Krush". The plugin will be used to work with WordPress XMLRPC for remote publishing from our content company. 2. The plugin will create a settings panel where users will create an account with "Kontent Krush". They will then be presented with a series of category options that we publish too. 3. There will be 4 levels of user access. "Trial", "User", "Enterprise" "Agency". Each has different access: Trial: Trial can only be used on one-blog and can only access the content category "trial". Trial will not cost any money User: User can only be used on one-blog and can pick any two categories. User will cost $47/month Enterprise: Enterprise can be used on up to 3 blogs, each can pick any 3 categories. Enterprise will cost $117/month Agency: Agency can be used on up to 20 blogs and pick unlimited categories. Agency will cost $470/month The payments should be auto-handled via paypal API, if the payment isn't made the users account must be disabled and no longer receive content. Users should have the ability to select which Wordpress category their incoming content goes into, and should be able to separate this PER incoming category. Admin Writing Panel: The admin plugin should allow us to write content in wordpress' WYSIWG editor, select the associated categories and then publish it out to any paying blog that is currently subscribed to that category in our database. The admin writing panel should also support "Spintax" if we write: "{This|Our} {blogs|post} rocks!" the client blogs will receive either: "This blog rocks!" "This post rocks!" "Our blog rocks!" "Our post rocks!" When submitting a bid: Please let me know that you have read this in detail by acknowledging that you can indeed work with Spintax. Our last dev started a project and later told me he could not.
