Teach me REST API testing using SoapUI, Groovy

Hi, this is not a classic project where you have to write code - in this project you will teach me how to test APIs using ReadyAPI tool (or SoapUI). I have some knowledge and practice with the tool so you need to go beyond the usual youtube video or vendor's tutorials - midlevel to advanced with good experience using scripting in Groovy. It would help me to chose you if you have projects to show your work and a broader experience on organizing a project. A decent command of English is required (no google translators). The only way to do this is by having sessions on TeamViewer to work on code while chatting (Skype or WhatsApp are ok) - please DO NOT bid if you cannot meet this requirement. I am in UTC-4 time zone and flexible with scheduling.
