I don't think you can achieve 10kpbs with 433MHz at 100m.
I have built few RF gadgets to control things on my land. They exchange short messages at 1kpbs. The distances are perhaps a little bit longer than 100m in some cases, and there's some trees in between. I used ready-made Linx modules, so there's not much of a cirucuit except two wires from MCU to the module and a wire from the module to antenna. Antenna helps a lot. I use simple ones, but you can use directional Yogi antenna. It is supposed to work better, but I haven't tried it myself. You also must use some narrow-bandwidth encoding, such as Manchester, otherwise it's totally hopeless.
