no worries as an old boss used to say: "there are many ways to put ink on 
paper."  Use what works for you....  
Just a thought:  sometimes it is faster to put the shovel down and rent a backhoe----  even if you have already been digging with the shovel for a few days.  The 'wasted' effort should be a learning experience - but similar to 2 wrongs never adding up to a right...  time once wasted by barking up the wrong tree can never be made up by continuing to bark up the same tree...  (and sometimes the 'quick-and-dirty' method is the best, especially on something you do infrequently.  just get the job through the shop so you can work on your bread-n-butter jobs.)
