The guy that you need to pattern your program after is Mike Palmer. He has posted a lot of really good stuff on raising and then wintering (what I call) summer nucs. It takes some learned beekeeping skills but its sure doable.
I love Mike's pattern. A caveat though. don't think - if you have a good winter - that you have mastered the process. there is a learning curve and I'm about 1/4 way through it. Having terrible survival this winter after great success last winter. I think it takes more skill than it seems when you read about it or watch his videos.
