[GTALUG] (OT) home renovation courses for home owner?

Very off-topic, but since most Linux guys are handy with their hands, so who knows... Are there courses for home owner who is thinking about doing home renovation? There are tasks that should be left for professionals. But, if the owner can do minor things, then it could be cost saving. Assuming he does the jobs right. Hence, the question. -- William Park <opengeometry@yahoo.ca>
