I may be able to advise here!
I have received a lot of funding to help set up what I am doing with wool and also work in funding as a consultant from time to time....will not bore you with that but suffice to say I know what to do to obtain it!
You will need evidence that the product is unique, needed urgently, works efficiently and would be something that cannot be bought easily already. The product you have developed as described on the other thread sounds good but get some people to test run it, when they have used it and got statistics, approach a large hatchery and let them trial it for further stats. If its all good and working out favourably write a report with quotes and figures that are watertight and provable.
Once you have this you are in a position to go for funding. You will find there is very little 100% funding and match funding is nearly always required. In kind match funding can be put towards some of it and providing you have the research docs proving the idea you may get funding to match grant funding through other bodies.
Believe me there is plenty of grant money out there BUT they do not give it to people with 'good ideas' but people who have proved their idea or product in some way, have evidence to show its needed and wanted!
Funders want to fund success stories.....so I wish you good luck!
