Odometer plugin with user input

Hi!

I’ve been looking for a plugin that shows a counter which can be affected by the user.
For example, the user wonders what a building project will cost.
He/she should then specify some parameters through input sliders/checkboxes, lists or something like that. And the resulting cost should change.

Afterwards i want the parameters that has been chosen to be included in a contact mail (but i figure i can do that with contact form 7).

Any ideas or tips? 🙂
