Tutorial for Developing SuiteCRM / SugarCRM

I'm a current admin for a SuiteCRM installation, and I manage customizations for our CRM. I am lacking a fundamental understanding of how to do simple development customizations for our website and further do not understand how to debug those customizations. I want to do this because our company currently outsources development with unsatisfying and often broken results. I would ask that you provide about 4-5 hours of tutorials via TeamViewer (Removed by Freelancer.com Admin) I am not a computer scientist, but as a former statistician who programmed Stata and R, I do have general understanding of programming. However, I'll still have to learn some fundamentals: 1) The optimal IDE for SuiteCRM customization 2) Git and GitHub (I don't know anything about this or how to use this) 3) The fundamentals of a SuiteCRM Installation (ie, what's the meaning of the important folders in the FTP) 4) Making developments, debugging, and loading back to the website instance 5) PHP/JavaScript Clarifications (I don't know anything about PHP) 6) Customizations along the lines of IF Variable X == Something, Variable Y is Required. 7) An optimal practice for testing the results
