only give a percentage of the profit ,not the selling price ( unless its really low ) a craft shop near me asked if i wanted to sell photos from their shop ,and they wanted half of the sale price ,i explained that it cost me money to produce them and if i only got half the sale price back i would make a loss on every single one ,they then changed their minds ,,,so unless you price them really high you might lose out
and i cant see a problem with selling pics with logo's in them ,think how many pictures would have black lines through them to hide shop names ,brand names etc,,,
