It won't get you published, but the first step I'd take is taking that word "manuscripts" out of quotes when talking about them. They either are or they aren't manuscripts!
On the other hand, SELF publishing is EASIER than ever.
Nobody can offer any real advice as to a next step in the process since they don't know anything about your manuscripts. Are they professional quality? What are they about? What age are they written for? How might they be pitched?
