Any business can be profitable, if you actually discovered what the people need.
And you have made a good research by knowing that this business can move in your area.....But my concern is, is your area a populated area ? Because if not, business might be slow.
Electrical stuffs do not get spoilt easily, one may use one bulb for almost a year and not get spoilt.....A socket could be used for more than 5months, i guess. I will advise you move this business to the market and start a wholesale not retail.
