Simple Room Design and Animation

We are putting together an educational website and we are looking to create short 2-5 second 3D animations on a continuous loop. The animations are of a sexual nature, showing various sexual positions. Each animation would involve 2 people, with a very simple design in a simplified room. We need you to design the room (like a bedroom or a living room) and create a male figure and a female figure doing a sex act. We are just starting out our project, and we have a limited budget set out for this project. I want to have you do a sample for us, and if we like your work we will have you more work for us. in the end we will be needing over 100 animations. I want to know how much time do you think it would take to create a sample for us, and how much would it be. Also, please give me some samples of your previous works, if possible. Please let me know if you want more information.
