If you do it on your own your looking to make a good earner out of it,if you employ 2-3 blokes all your looking for is turnover or break even.As long as there making the guys wages and a small profit for overheads they will be happy,this is the way commercial is getting,i have had national firms trying to muscle in on me over the last couple of years but the managers keep them away,that`s the key to keep in with those concerned ie the odd bottle of wine at xmas.
