strategy to convert science to money (transmitting science)

[psyper]

When I start out a save I give myself loads of science, max out the tech tree, and then set what is left to zero. This way I'm playing ksp from a space-x point of view - all the technology is there, I just have to design and test the craft I use to fulfil contracts. As such I've set up the strategy to convert a portion of science I get from contract in to cash (basically selling data to 3rd parties). This works okay when I recover craft but doesn't seem to be working when I transmit the science. I basically want to collect science to sell as an extra income. How do I go about doing this?

Contracts and/or mods. As best I'm aware, the science taken directly from biomes is not convertible in stock.

This is during normal science gathering. Maybe I've misunderstood as I usually do contracts while on a mission and bring back a load of science. Is it the science gained from just the contract that gets reduced by the strategy or is it all science I bring back?
