Wordpress Plugin Customization for Membership Site

I want to build a site with multiple authors/writers to post articles, make money from posting articles. Authors may set articles as Free, Paid to view or buy yearly membership plan to view. I've bought wp membership plugin that capable to get this done, here I temporary named the plugin-XXX However, as master admin I need to pay authors based on their income. plugin-XXX only has full reporting, but it doesn't have individual reporting for separate authors. I can't let authors to view full reporting, they should able to view own sales only. That is the reason I want to build this plugin. The customize new plugin should has below functions : 1) Author able to view own sales transaction report. 2) Author able to request income withdrawal (from me - Master Admin) 3) Me as master admin able to approve withdrawal, update withdrawal details for author request. Update payment details like amount, date, reference number, transaction number, bank name, bank account number, remarks and etc. 4) Readers who pay to view articles or subscribe to membership will able to see their purchased articles and payment history. ***** ***** ***** ***** ***** ***** What you need to do? You should build a standalone new plugin that pull sales data from plugin-XXX and codes the functions as I mentioned above. I DO NOT want you to modify existing plugin-XXX because this will crash when it auto updates. ***** ***** ***** ***** ***** ***** Please bid only if you have at least 3 years of Wordpress plugin customization experience.
