Develop DotNet Core validators and formatters encapsulation

Dear DotNet Core 2.1 developer, I am looking for a professional with experience in DotNet Core 2.1, Autofac Dependency Injection, and NUnit unit testing (with Moq when appropriate), to develop the following: Encapsulate some formatters and also some validators into a single class library, exposing standardised methods to manipulate them. Attached is a detailed specification with the requirements. I would like to work on hourly basis, with screenshot monitoring, but keeping a limit on the price of the task. I will supply you sample code on how to implement validators, as well as a skeleton for the application architecture which you should customize to implement this task. This task should be completed in 4-5 days. Please submit your bids.
