Requeening 1 of 2

As I have had some problems with aggressive bees this year I am going to re queen in the spring, when, hopefully, the numbers in the hive are lower. Given that the bees are aggressive what is the best way to requeen with the least amount of manipulations?

Please bear in mind that I only have weekends and evenings to carry out manipulations!
