VFX for an educative project

Hi, we are trying to add some effects, but we are not good at it. So we want to hire someone to do the following: - Add a crowd of insects that crawls from a hand, those can fall from the hand at random times, like if we have 1000 insects, 10 or 20 would fall at a random. At one point we would like to have a complete hand made of insects, that walks over themselves. - a realistic bird that leaps away, that starts with folded wings on the ground then flies away - a m14 that falls and shots multiple times while bounces at the floor. All of those clips go on a videoclip that we will provide. At this point we would want to know how much each single shot would cost, on an average of 20 seconds per shot, in 4k resolution output. We need VFX experience, also creature animation experience, and photorealistic rendering, please refer your related portfolio, NO motion graphics or architectural rendering, as we are not looking for that. ****Everything will have to be as realistic as possible, and made in 3D*** As we said, we want to know first the cost of each shot, as we understand it might cost more per shot, and then we would post the project with the real estimate. If you bid be sure to have experience and be fully able to achieve what we want.
