HI there and welcome to our forum.
You can try to get into a BSN program tailored to people with prior baccalaureate degrees. The problem is, most of these are compacted, intense full-time programs and you say you have no time for that. You could check out universities in your area that offer nursing degree programs and ask if they offer any part-time programs. I will caution you, most firsttime nursing programs do NOT offer part-time programs, particularly during clinical experiences/components. You will need to be able to dedicate a lot of time to clinical experiences in hospital/long-term care and other medical settings and preparation for these. Nursing programs are surprisingly time-consuming and many people who have prior degrees are very surprised by how much tougher getting a degree in nursing can be.
What you have going for you, is the prior degree. You probably have a LOT of the requisite pre-nursing courses needed already.
One more other option that may not appeal to you but some do anyhow is to check out community colleges in your area to see who offers an associate's degree in nursing. You can get an ADN and go on to work on an online RN-BSN/MSN later.
I guess a lot depends on how time and money you have to dedicate to nursing school.
My advice like I said, go to a university or community college and see what they offer and how they can help you.
