Web Developer needed to create a calculator to be embedded in marketing website

We are looking for the development of a beautiful calculator so that visitors can visualise how much they can earn from our rewards program.



The page visitor should be able to:

- Select the currency (GBP or EUR)

- Enter total spend (in the currency selected, by keying in number)

- Drag sliders below (0-100%) to allocate the total spend previously entered across categories we provide

- See the total monthly and annual cashback in the selected currency using a formula that we will provide the developer



This needs to be included in an existing Webflow website and should be optimised for quick load times.
