I was looking for someone to get me started or show me how to make a plugin that accepts Monero for subscriptions in 2.0.15 (and functional for 2.1x), here's what it needs to do.
1. Let user pick a subscription
2. Generate new Monero wallet
3. Display wallet address
4. User pays
5. When payment is confirmed transfer funds to my specific wallet
6. Apply subscription to currently signed in account
I know with the small handful of Monero PHP libraries availible this shouldn't be difficult, I've done work with Python, HTML, and CSS but never PHP. I'd be willing to pay whoever writes this for me Monero in the future when I get going.
