I only did that for the families/genera. Though sometimes I went to species when there were only a few in the genera (blandings, wood turtles, etc.). Probably spent about 50 hours over 3 months to get it presentable for invites. And then had a ton of revision for regionals and states. Didn't do as much for nats, though (and I guess it showed a little..).
