Four of 5-second animations

I need four of 5-second simple line-drawing animated GIFs The purpose of each animation is to demonstrate the practical use of a product, alongside the product description text on my website. Each animation is to be no less than 50 frames. Each has only five scenes on the storyboard, which are a variation of the points below. I will give full details. 1. Hand and tool reaching into bucket to pick up product 2. tool and product being applied to vertical surface 3. vertical surface being splattered with dirt 4. hand removing product from vertical surface, showing clean surface beneath 5. gleaming clean surface The main goal is to demonstrate the product quickly in an interesting way. The style needs to be simple without being childish. I want a bit of personality on the website, all the other competitors product demonstration videos take too long and are boring. All bid submissions must show a still sketch of a hand holding a tool of your choice. Bids without a sketch will be ignored.
