Yep, good luck Stu
But I hope you've put in a weekends practice on your own house and a few other close friends and family first!
There is a big learning curve and it will bite you in the backside if you ain't careful
If you are going out and winging it, take your time, take your ladders, and go back and check and re-check your results.
As each day passes you'll need to check your results less and less as your confidence and ability grows.
Welcome to the fold
