I am concidering starting a part time business at home sharpening lawn mower blades. There seems to be a shortage of this service in my area.(Except for the shops that will do it on a bench grinder). I have been lookin at the Magna-Matic Lot#4 (uses the series 8000 sharpener). I am looking for any help or suggestions from equiptment to advertising. Any help woul be greatly appreciated. Thanks.
