Revenue calculator needed for wordpress in the next 24 hours

I need a revenue calculator added to a wordpress website. It is a property management company and we want a calculator like the one on the homepage of this company: https://www.passthekeys.com/en/ or this company https://www.smarthost.co.uk/

It should work in the exact same way, I assume these companies have it linked to the Airbnb calculator here:

Please start the message with Mario. I will not reply otherwise. Thank you :) I was told this is one hours work so the budget is £20.

Thanks
