I am not sure if this is practical.
Aren't you better off doing a good job on a few things and be happy you buy some of these things cheaply.
I think you have a good idea on trying to capture additional value.
While everyone is different, investing some time and energy on new business development is a sound strategy...especially if it takes away some of the risk with monoculture....
Some of our pork producer friends here in Ontario are taking their pork and marketing it directly to consumers with some really innovative marketing approaches to capture additional value.
One of our my other friends is developing some additional services that utilize his time and equipment in the winter months that will generate additional revenue.
Good ideas and very innovative.
Here is a clip on some profitability strategies from the Top Managers team.
Hope this helps,
