Minidumps analysis with WinDbg

I need to acquire knowledge about Minidumps (.dmp) analysis with WinDbg: understand the crash, identify malware, etc. I did my first steps: I am good identifying the region of memory where is the issue but after that, I don't know how to continue. Is not necessary to work directly with WinDbg: also possible work with IDA Pro with WinDbg as debugger. I want to receive particular classes: 20€/h, minimum 5 hours.
