How much can a data replacement script cost, depending on which page a person originally opened?

Question

JavaScript

Greetings.

Interested in the approximate cost of writing a script for an average programmer. The essence of the script is as follows.

There are three pages on the site (conditionally, to facilitate the perception of the issue):
- contacts
- a page about bricks
- a page about stones

On the contact page there is a block with the image of sand and the text: buy sand .

Action options:
A) If a person opened a page about bricks and then went to the contact page, then the image of sand changes to the image of a brick , and the inscription buy sand changes to the inscription buy brick .
B)If a person visited the page about the stone and then went to the contact page, then the image changes to the image of the stone , and the inscription changes to buy a stone .

Earlier on Toaster it was recommended to use: History API, Session parameters, localStorage...

Question: how much does it cost on average to write such a script for a site?

Answer 1

I think that for 1000 rubles you will find the right person, because. the task is quite simple.
