Just as the others said, Hack is really better suited for a self, plus its a lot less work. Keep the limbs about 2" wide for at least the bottom half then taper it to 3/8" at the nocks and you are set design wise.
A holmgard is also possible but probably not a great idea for one of your first bows.
I've made a couple hack bows that worked fine as selfs (even in my naive early stages of making bows). If I was making another one (which I will do someday soon), I'd go self.
