GoLang Expert who has experience in Trust Wallet Core Library -- 3

I am going to use Trust Wallet libraries(trustwallet.com) in my website as a backend.
I know it's a frontend library but for MVP of my project, I need to use it as a backend.
I saw the GoLang solution for integrating it into backend.
https://developer.trustwallet.com/wallet-core/integration-guide/server-side

And here is a GO sample in their public github.

I need someone who can implement GoLang solution of trust wallet library so the backend handles incoming and outgoing transactions by using trust wallet library.
The purpose is to make use of all of the trust wallet's functionality in the backend.
So your first task is to implement transactions between end user and server wallet.
So userA sends X amount of token to server wallet, then the server wallet receives it and send it to userB.
This is simple but really important.
If you succeed in the first task, then you will be chosen to implement all other functionalities of trust wallet library in the backend.
So for this first task, my budget is around $50.
And for upcoming tasks, we can discuss later.
Hope to talk to you soon!
