Any good video courses for ReadyAPI ?

I am looking for paid (affordable) or free video courses which cover basic and advanced examples in ReadyAPI. I tried the basic one by SmartBear here - https://www.youtube.com/playlist?list=PLrA5ciulugn_w0pW1_SSyfucD-k5Fasj_. But, it is too simple and does not represent what one would see at a job. I am looking for a ReadyAPI video tutorial which is similar to or better than this SoapUI tutorial here - https://www.youtube.com/playlist?list=PLhW3qG5bs-L-Bt9T_bnyflQ0Te4VgFhKF. Main focus of the tutorial should be ReadyAPI and API testing. Most of the examples should be for REST APIs & very little SOAP api. I am not looking for lessons on Groovy and SQL.

Do you know any such video tutorial which is under 150 US dollars and can be accessed for at least 1 year?
