I think you should get your case assessed by another MARA agent, with the chance of your occupation being added to any of the state occupation lists, and to get a proper assessment of your points.
Work experience points is generally only post qualification, your qualification may not be at a high enough level to receive points, partner skills requires an occupation on the same list and a positive skills assessment. If your partner does have an occupation on CSOL and is able to gain a positive skills assessment it may be an option for them to be the main applicant.
