As far as I know from my conversations with the Bahmni team those skills are expected as per-requisites for a Bahmni implementation. There is no training course for those things provided by this project.
I am not sure if this is the case for all courses. Anyway, their paid pay plan includes an option to apply for a “Financial Aid” program. See this screenshot:

As @janux says, those specific technical skills are prerequisites that you need to configure various aspects of Bahmni. It’s also possible to do some parts of the implementation/configuration with just a general technical skillset of being able to follow commands listed in the documentation.
We don’t have an online implementer training at this point, though there’s lots of implementer documentation in the Implementers Guide in the Bahmni wiki. What are you looking to do exactly?
