Air National Guard is always one way. It'll take awhile, but you can get there without a CFI/II/MEI. Thats where I am at in my life. Didnt really wanna go the regional route, but when you need insurance you need insurance.
Also I would agree about the meet someone who has a plane and fly with them. If you can really get buddies with an old dude who doesnt give a sh!t about hours he'll let you log it.
If you can become friends with a dealer and he wants you to do deliveries that would be great too.
These are all things that I have done to get hours. Here I am prepping for interviews with regionals and flyin heavy metal!!! All without a CFI.
