So these are all the PNP streams which you can be eligible for without job offer, canadian experience, canadian education or any entrepreneural process:
Among these, only Saskatchewan, Prince Edward Island and Nova Scotia are accepting manual application, you need to watch those streams and apply when they are opened (I believe PEI is always open for submission)
Saskatchewan:
https://www.saskatchewan.ca/residen...nal-skilled-worker-saskatchewan-express-entry
PEI:
https://www.princeedwardisland.ca/en/service/submit-your-expression-interest-profile
Nova Scotia Category B (currently closed):
https://novascotiaimmigration.com/move-here/nova-scotia-demand-express-entry/
As for the Atlantic program, you're right, you need a valid job offer, sorry for that.
Hope this info provides some help, I'm in no way an expert, I just got my OINP nomination through EE but I've read all these info online during my waiting time in EE pool to explore my chances. So, you might want to ask for the opinion of a professional but beware, most people get nothing in return for their money from the so-called immigration consultants.
