I have thought about subbing out for years. I as of a couple of years ago started to deal in this. Yes a sub and a employee both can be in the same category but if handled proper I think in time it will work. I'm 47 now and if I were to sub all types of lawn care I could be semi retired one of these days and do this forever as long as my health hangs in there. I have a amount I need to get to for this to work out at 20% per job. It will take 300 lawns to make it work for me.
