Thank you so much @Robert Cemper for trying to help me. 

I want to implement UPS API in a webservice platform using the language that I mention in my post. I have made multiple research, read document and examples from UPS web developer. I already have my Access Key and all the APIs zip files downloaded from UPS. However, all post that I found online, including the one you suggest me doesn't give the basic start step such as how to connect my API to UPS server using Json or PHP files for instance. My APIs will be using for United States. I need to implement the API for the Address Validation, Pickup, Rating and Shipping.

What I am looking is an experience (paid or volunteer) developer tat can help me to start my project and understand the steps.

Awaiting your reply!
