I need customised bespoke illustration animation

NB NOT Whiteboard, logo, or template animation. This is for bespoke customised animation. ONLY quote if you are experienced in this field. I will need to see examples of this type of work and NOT templates etc.
***********************************************************************************

I need 10 - 12 simple graphics which need animating on screen, such as line graphs, and squares being move around the screen. . I need to get an idea of your understanding and pricing. Each animation will be different, but are simple geometric shapes and lines. No drawings or characters. Files will be used in videos intended to stream online, and will be combined with an on-screen presenter. Would you provide these with an Apha channel? Do you have any sample files you can share with me?

I have no idea on pricing, so please provide a quote for the 2 examples shown. Thank you.
