You are soooo lucky to be able to be there and see it all and actually get your hands dirty on your own build. Sorry if you have mentioned this before, but is this arrangement because you just live close by or have you worked together before or just friends, all of the above???
Anyway, not only do you get a build done for you, you are right there, that is just a total step above the rest!!!!
And to have such fun on top of it all without artificial enhancements (not that there is anything wrong with that
), that is just awesome.
