Can I Integrate a Pricing Slider on my website?

I offer an editing service, and clients pay based on the word count in their document, so if their document is 1400 words, they can drag the slider to 1400, and they are given an amount that I have set that reflects the number of words they have selected.

An additional option would be a drop and drag for their document that automatically calculates the word count, and calculates the price.

I am fairly certain that the below website was made on Squarespace (I could be wrong), and they have exactly what I am looking for.

Also, it would need to be integrated in the payment page so that the price they are given on the slider transfers to the payment page as well, so that they can pay the quoted price when submitting payment.

Is this at all possible on Squarespace, or am I dreaming?

Many thanks!

The site you've linked is a WordPress site.

Squarespace isn't a very practical solution for this because product prices are fixed, so you'd need variants for each word count range.

Hmmm...that's certainly not the answer I was looking for, but I thank you for your knowledge, nonetheless!

If you are looking for quote generator only (mean the invoice will be manually sent to customer), then the custom code injection can be used to twist the calculation and send the selection to email or mailchimp. Things like this can be achieved using Squarespace with code injection
