Stiff rims are fairly easy to work with, so the ones you've got would be good ones to start with.
Wheel building stands are handy but for an occasional build, you can use your frame/forks and a couple of tywraps used for assessing the runout whilst truing and tensioning. Ive done 3 sets recently in the frame.
If you have a modicum of patience and can methodically follow the steps, you could try a DIY build
