Perhaps you need to look at the tech company perspective. They have to make a profit on the development of expensive hardware and software, and they may not sell many units -- it's not exactly a mass market. So of course it makes sense for them to go after deep-pocketed corporations, rather than small farmers. Rather than expect developers to think like a small farmer, try framing your pitch to developers in terms of how they can fund their development, and how they can then scale up sales volume to justify their investment. Or, try organizing the farmers to form some kind of entity that has numbers and money behind it, to attract the attention of developers.
