I would like to see a stock photography agency that markets its portfolio direct to the customers.
Like, they ring designers, make appointments, turn up and go over the features and benefits of dealing with them direct to a buyer. Build a relationship with faces and actually see what the designer is doing.
In the USA, I am sure they could focus on NY or LA and find so many sales they never knew existed. Sell subscriptions, or ad-hoc sales.
Good old fashioned sales theory.
