Hi Migrateous -
Sorry, but there are far too many parts of your application I know nothing about - impossible to give you any kind of specific advice as to whether you should lodge a visa application or not. Skilled PR visas are complicated animals - many moving parts, and complex issues such as whether your work experience will be assessed as closely related to your occupation (check ANZSCO specific details, etc for this). There are dozens of ways a PR application like this can go wrong, so it's critical that whoever is giving you advice have access to all the facts and documents for your case.
Sorry I couldn't help you any further at this point - if you'd like organise a professional consultation, you can contact me here via PM or click on my website in the signature below.
Best,
Mark Northam
