RVN payment system

How would I go about on getting someone to make me a payment system that accepts RVN coins as payment?

​

I run a few Rust servers and I'd like the players of the server to be able to buy in-game perks, kits and other privileges on the server, but I want the payments to be in ravncoin and automated.

So basically PlayerA buys a VIP Package for lets say 100 ravencoins. They send me 100 coins, and they're automatically placed in the VIP oxide group on the server. Fully automated process. After 1 month (30 days) they can send another 100 rvn coins to extend their VIP package for another month or if they choose not to they'll automatically be removed from the VIP group.

It also needs to be based on market price. So 100 coins at $0.07 is basically a $7 package. So if raven goes to $0.14 then they'd only need to send 50 coins.

I don't even know where to look to have someone build me something like this. Where can I start?
