DNP or Post Masters?

I am currently working on my masters in nursing education. I really wanted to get my family nurse practitioner degree, but I have a time frame to get my masters and still teach in my nursing (ADN) program, so I went with Phoenix to get the MSN since the other programs were already full or I missed the deadlines.

As soon as I am finished (probably late fall), I want to work on the FNP (my goal is to teach part time, like I do now and work as FNP, I already have a job lined up, working with the Amish/Mennonite in a clinic, which I have done in numerous ways over the past few years).

My question is whether it's better to get my post masters in FNP or to just get the DNP and if that's even an option? Or do I need the post masters first before even looking at the DNP? I'm thinking if it's going to be made mandatory and I can go straight to that, that might save money and time in the long run.

Also, what are some good online programs that can be completed in a year or so? I looked at U. of S. Alabama and liked there's, but it looks like I'd have to wait until next fall to start.

Anyone know of programs that have rolling admissions (like Phoenix does, which is great for people like me, I love that aspect).

Thanks! I wouldn't be in such a hurry to even get finished, but my husband got sick with a brain tumor in the fall and I am going to have to be the primary breadwinner soon (we have 5 kids), so I can't drag school out like I had originally planned. I need to get it finished and get working!
