You have six months to respond to the NOI & once you accept,you have 14days to submit all the documents & fee ...
so, it may be wise to recreate if you are really confident of getting together all the docs required by OiNp..and it seems a lot to me...
Visit their site and you'll find the application...with all the details on how to go about it and what all docs required...if you are confident of organising everything then go PNP way...u need $1500 too..

however at 403 u hold fairly good chance of a far simpler ITA through EE regular draws....in the meantime try if you can improve ur score by getting a CLB10 / CLB9 equivalent IELTS
