Animation for social media start-up

Hello, I am looking for a skilled and imaginative animator to create 2 separate but related demo videos for a start-up business. Each video should be approximately 2 – 2.5 minutes long. The purpose of the animation is to provide a visual explanation of the product and business model. The video needs to contain a clear voice, sound, company logo, effects and creative graphics. Ultimately, I need something that will convey the vision of the founders. The video has to be super clean and contain simple creative animation. We are a startup; therefore we have a relatively small budget. In addition, anyone taking on the project must sign a non-disclosure and respect our confidentially agreement. Animator must send a storyboard, prior to beginning video, for approval. Below are sample of animation we thought would be a good representation of what we are looking for.
