3D animation of microwave of a unicycle

I need an animation of a microwave riding on a unicycle. The unicycle should move around in a circle. The animation would be approx 3-4 secs long and it should start and end in the same position so I can loop it if necessary. Dimensions 1080x1080 pixels, 25fps. See test animation for ref. On the test the microwave just moves side to side but I would need it doing a circle. Also I wouldn't want the seat to go up and down. I can supply 3D models of the unicycle and microwave. I want it to look as realistic as possible for a limited budget. The background and floor should be white with some natural looking shadows on the floor. I'll also need it supplied without floor and background with an alpha channel. The viewing angle should be similar to the ref video.
