WordPress / Build Monthly Subscriber

Need to add Monthly Subscriber Page and Functionalities as follows: 1. Admin will uploaded Report(PDF) from backend every week. 
 2. Report can be shown on My Account & send a copy via mail. 3. Payment Gateway would be common (PayUmoney). 
 
 4. Subscription can be done Monthly, Quarterly, Half-Yearly & Yearly. 5. Subscription Expiry: If the user has subscribe for 1 month then until the subscription get expired, user will get the 
report on “Report” section of the dashboard just after the upload done by admin. All report subscribers will get notification email that the new report is ready to view. If the user will not renew the subscription, then the user will not get next uploaded report. Now, if the user subscribes after 2 months of expiry, then the user will get the report from active subscription. Hence, no report can be visible of in-between the expiry period. 6. Report Subscriber shall get reminder email before renewal 7 Days before, 2 Days before, 1 Day before. Note: This is an update to existing website, subscription page & my account is already created, you need to add this module as per the requirement.
