Discord Subscription & Payments Management

Hello, I am looking for a Discord Automation tool to automate Subscription management and process payments in CryptoCurrency (BTC, ETH). What is required is that any member can message this bot and receive a welcome message with membership options, User select the membership option he is interested in and bot provides a payment address for BTC, ETH. Once member make the payment, it confirms the payment ans subscription and assign relevant role to user based on membership selected for the time period selected(1month, 3month, 6month, and 1 year). When a user's membership is about to expire, bot reminds user 3 days in advance, then 1 day in advance, then 12 hours, and then after exired. It should also allow to pull a report for all users currently subscribed with their duration by admins and allow admins to modify any subscription time with commands like giving grace periods and trials.
